The WordPress White Screen of Death (WSOD) is a common error that can be caused by a variety of factors. Here are a few things you can try to troubleshoot and fix the WSOD:
1. Check for plugin conflicts: Deactivate all of your plugins, and then activate them one by one to see if any of them are causing the WSOD.
2. Check for theme issues: Switch to the default WordPress theme (e.g. Twenty Twenty), and see if the WSOD goes away. If it does, then the problem may be with your theme.
3. Check your .htaccess file: Your .htaccess file controls how your website functions, and a corrupt .htaccess file can cause the WSOD. You can try renaming your .htaccess file to something like .htaccess_old, and then see if the WSOD goes away.
4. Check for a PHP error: The WSOD can sometimes be caused by a PHP error. You can check your website’s error logs for any PHP errors that may be causing the WSOD.
5. Increase the PHP memory limit: If none of the above solutions work, you may need to increase your PHP memory limit. You can do this by adding the following line of code to your wp-config.php file:
If none of these solutions work, you may need to seek further assistance from a WordPress developer or the WordPress support team.
