It enables website administrators to create and manage multiple sites using one centralized WordPress dashboard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, while converting a standard WordPress installation into a <a href=\"https:\/\/developer.wordpress.org\/advanced-administration\/multisite\/\" target=\"_blank\" rel=\"noopener\">Multisite network<\/a>, you may encounter the

database.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are trying to configure a new Multisite network, this existing configuration may prevent you from proceeding with the setup.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this guide, we will explain how to identify the existing WordPress Multisite configuration and resolve the warning by reviewing the <code>wp-config.php<\/code> file, checking the database tables, and updating the <code>.htaccess<\/code> file.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Follow the steps below carefully to troubleshoot the issue and proceed with

class=\"wp-block-heading\">What Causes the Existing WordPress Network Warning?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The warning can occur when WordPress detects an existing network configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some common causes include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Existing Multisite configuration constants in the <code>wp-config.php<\/code> file.<\/li>\n\n\n\n<li>Previously configured Multisite database tables.<\/li>\n\n\n\n<li>An incomplete or interrupted Multisite setup.<\/li>\n\n\n\n<li>Old network configuration remaining after a previous Multisite installation.<\/li>\n\n\n\n<li>Existing network settings that were not properly removed.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Before making any changes, identify whether the WordPress installation already contains an active Multisite network.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 1: Check the wp-config.php File<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">First, log in to your server using SSH or access your WordPress installation through the hosting control panel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Navigate to the WordPress root directory and open the <code>wp-config.php<\/code> file.<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">nano wp-config.php<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Check whether the following Multisite configuration constants are already present:<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">define('MULTISITE', true);\ndefine('SUBDOMAIN_INSTALL', false);\ndefine('DOMAIN_CURRENT_SITE', 'rainbowcreed.dev');\ndefine('PATH_CURRENT_SITE', '\/');\ndefine('SITE_ID_CURRENT_SITE', 1);\ndefine('BLOG_ID_CURRENT_SITE', 1);<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">These constants enable and configure WordPress Multisite functionality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are resetting an existing Multisite configuration to create a new network, review these settings and remove the old Multisite constants only after confirming that the existing network is no longer required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Important:<\/strong> Do not remove these settings if you intend to continue using your existing Multisite network.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 2: Take a WordPress Database Backup<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before modifying the WordPress database, create a complete backup.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can use phpMyAdmin or the MySQL command line to export the database.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Example:<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">mysqldump -u root -p wordpress_db > wordpress_backup.sql<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Replace <code>wordpress_db<\/code> with your actual WordPress database name.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You should also back up the WordPress files, especially:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>wp-config.php<\/code><\/li>\n\n\n\n<li><code>.htaccess<\/code><\/li>\n\n\n\n<li>WordPress installation files<\/li>\n\n\n\n<li>Uploaded media files<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A backup helps you recover your website if anything goes wrong during the configuration process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 3: Check WordPress Multisite Database Tables<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Next, access your WordPress database using phpMyAdmin or the MySQL command line.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Select the appropriate WordPress database and check for the following Multisite-related tables:<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">wp_blogs\nwp_blog_versions\nwp_registration_log\nwp_site\nwp_sitemeta\nwp_signups\nwp_sitecategories<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">These tables are commonly associated with WordPress Multisite installations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Note:<\/strong> The database table prefix may not always be <code>wp_<\/code>. Your installation may use a custom prefix.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can check whether these tables exist using the following SQL query:<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">SHOW TABLES LIKE 'wp_%';<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">To check specific Multisite tables:<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">SHOW TABLES\nWHERE Tables_in_wordpress_db IN (\n    'wp_blogs',\n    'wp_blog_versions',\n    'wp_registration_log',\n    'wp_site',\n    'wp_sitemeta',\n    'wp_signups',\n    'wp_sitecategories'\n);<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Replace <code>wordpress_db<\/code> with your actual database name when using the query.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 4: Remove Old Multisite Configuration (Only If Resetting)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you have confirmed that the existing Multisite network is no longer required and you want to completely reset it, you may need to remove its old database configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following tables are associated with Multisite:<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">wp_blogs\nwp_blog_versions\nwp_registration_log\nwp_site\nwp_sitemeta\nwp_signups\nwp_sitecategories<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Before removing any tables, make sure you have a verified database backup.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Warning:<\/strong> Dropping Multisite tables can permanently remove network configuration, site registrations, and other network-related information. If the existing network contains websites or data you need, do not execute these commands.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the network is confirmed to be disposable, the following SQL commands can be used:<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">DROP TABLE IF EXISTS wp_blogs;\nDROP TABLE IF EXISTS wp_blog_versions;\nDROP TABLE IF EXISTS wp_registration_log;\nDROP TABLE IF EXISTS wp_site;\nDROP TABLE IF EXISTS wp_sitemeta;\nDROP TABLE IF EXISTS wp_signups;\nDROP TABLE IF EXISTS wp_sitecategories;<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Execute these commands only after confirming the correct database and table prefix.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Important:<\/strong> This is a destructive reset, not a routine fix. Do not use it on a production Multisite installation that you want to preserve.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 5: Check and Temporarily Move the .htaccess File<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Next, navigate to the WordPress root directory and locate the <code>.htaccess<\/code> file.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can temporarily rename it using:<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">mv .htaccess .htaccess.backup<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">This preserves the original file while allowing you to generate fresh rewrite rules later.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <code>.htaccess<\/code> file contains Apache rewrite rules that help WordPress process website URLs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Remember that removing or renaming <code>.htaccess<\/code> alone does not remove an existing Multisite database configuration. It is a separate troubleshooting step.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 6: Log Out and Log Back Into WordPress<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">After reviewing the configuration file and completing the required reset steps, open your WordPress administration dashboard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Log out of your WordPress account and log back in.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Navigate to:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Dashboard \u2192 Tools \u2192 Network Setup<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Check whether the existing network warning has disappeared.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If WordPress still displays the warning, recheck the configuration constants and database tables to identify any remaining Multisite configuration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 7: Configure WordPress Multisite Again<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Once the previous configuration has been safely cleared, you can proceed with the new Multisite setup.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Navigate to:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>WordPress Dashboard \u2192 Tools \u2192 Network Setup<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Choose the required network structure:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Subdomains: Create websites using subdomains.<\/li>\n\n\n\n<li>Subdirectories: Create websites using subdirectories.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Subdomain structure:<\/strong><\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">site1.example.com\nsite2.example.com<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Subdirectory structure:<\/strong><\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">example.com\/site1\nexample.com\/site2<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Select the appropriate option based on your website requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Follow the instructions displayed by WordPress to complete the Network Setup process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 8: Update the wp-config.php File<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">After completing the Network Setup process, WordPress will display the configuration code required to enable Multisite.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Copy the generated configuration and add it to your <code>wp-config.php<\/code> file.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The configuration should be placed above the following line:<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">\/* That's all, stop editing!

What does &#8220;An existing WordPress network was detected&#8221; mean?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This warning indicates that WordPress has detected an existing Multisite network configuration. It may be caused by Multisite constants in the <code>wp-config.php<\/code> file or existing network-related database tables.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. How do I fix the existing WordPress network detected warning?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">First, check the <code>wp-config.php<\/code> file for existing Multisite configuration constants. Then inspect the database for network-related tables. If you are resetting the network, safely remove the old configuration after taking a complete backup.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Which database tables are used by WordPress Multisite?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Common Multisite-related database tables include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>wp_blogs<\/code><\/li>\n\n\n\n<li><code>wp_blog_versions<\/code><\/li>\n\n\n\n<li><code>wp_registration_log<\/code><\/li>\n\n\n\n<li><code>wp_site<\/code><\/li>\n\n\n\n<li><code>wp_sitemeta<\/code><\/li>\n\n\n\n<li><code>wp_signups<\/code><\/li>\n\n\n\n<li><code>wp_sitecategories<\/code><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The table prefix may vary depending on your WordPress database configuration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related Articles<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/pheonixsolutions.com\/blog\/how-to-install-update-wordpress-automatically-without-using-ftp\/\">How to Install \/ Update WordPress Automatically Without Using FTP<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/pheonixsolutions.com\/blog\/fixedyour-php-installation-appears-to-be-missing-the-mysql-extension-which-is-required-by-wordpress\/\">Fixed:Your PHP installation appears to be missing the MySQL extension which is required by WordPress.<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Need Help with WordPress Multisite Setup and Configuration?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Need assistance with WordPress Multisite installation, network configuration, existing network warnings, database issues, or <code>.htaccess<\/code> troubleshooting?
