The WordPress white screen of death is one of the most common WordPress errors. It is also one of the most frustrating ones because there is no error message, and you are locked out of WordPress.
Please follow the below steps when you see a blank screen like below.
- Take the backup of the site and the database.
- Increase the memory limit.
- Deactivate all plugins by logging to wp-admin.
- Replace the theme with the default theme.
- After doing all the above once again check the site. It should work.
