How do I check WordPress core file integrity in Plesk?<\/h3>\n\n\n\n<p>Log in to Plesk, open the required WordPress installation in WordPress Toolkit, select <strong>Check WordPress Integrity<\/strong>, and click <strong>Verify Checksums<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. What does Verify Checksums do in WordPress Toolkit?<\/h3>\n\n\n\n<p>It compares WordPress core files against their expected checksums to identify files that differ from the reference values.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Does a checksum mismatch mean my WordPress website is hacked?<\/h3>\n\n\n\n<p>No. A checksum mismatch means that a file differs from the expected reference. It may result from manual modifications, corruption, incomplete updates, or unauthorized changes. Further investigation is needed to determine the cause.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Can I restore modified WordPress core files through Plesk?<\/h3>\n\n\n\n<p>Yes. Where supported by the installed WordPress Toolkit interface, you can use the <strong>Reinstall WordPress<\/strong> option to restore core files. Review the operation details and ensure that a recent backup is available before proceeding.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Will reinstalling WordPress delete my website content?<\/h3>\n\n\n\n<p>Reinstalling WordPress core files is intended to restore the WordPress core, but the exact effects depend on the operation and Plesk interface. Review the confirmation details and take a complete backup before proceeding. Do not assume that all website files and customizations are unaffected.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. What should I do if checksum verification fails?<\/h3>\n\n\n\n<p>Review the affected files, determine whether the changes are expected, and investigate suspicious modifications. If corrupted or unauthorized changes are confirmed, restore the appropriate core files and perform a security review.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Should I back up my website before reinstalling WordPress?<\/h3>\n\n\n\n<p>Yes. A recent backup of the website files and database is strongly recommended, particularly for production websites. Verify that the backup is available and usable before starting the restoration process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8. What if checksum mismatches return after reinstalling WordPress?<\/h3>\n\n\n\n<p>Investigate the underlying cause, including possible compromised credentials, vulnerable plugins or themes, unauthorized access, and automated file modifications. Repeatedly reinstalling core files without addressing the cause may not resolve the issue.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related Articles<\/h2>\n\n\n\n<p><a href=\"https:\/\/pheonixsolutions.com\/knowledge-base\/2026\/09\/18\/how-to-add-a-user-in-plesk\/\" target=\"_blank\" rel=\"noreferrer noopener\">How to Add a User in Plesk<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/pheonixsolutions.com\/knowledge-base\/2026\/09\/21\/how-to-create-a-user-role-in-plesk\/\" target=\"_blank\" rel=\"noreferrer noopener\">How to Create a User Role in Plesk<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Talk to Our Technology Experts<\/h2>\n\n\n\n<p>Need assistance with WordPress core integrity checks, Plesk configuration, or website security?
