define (‘WP_DEBUG’, true) :

In the wp-config.php file, we will set the value of WP_DEBUG to true. In this way, we will activate the error messages, and it should be shown on the screen which error is causing the WordPress white screen of death. So now we can go to that line and fix accordingly.

So, you have done all the step above still but failed to log into the wp-admin to change the plugin or theme name. How to do it?

Use FTP / Hosting Control Panel File Manager.

• Go to your website hosting control panel or log in using FTP. Now, navigate to the wp-content folder.

• Rename wp-content/themes/YOURTHEME folder to something else. Like ‘ YOURTHEME-DUMB’.

• Now go and check if you can log into wp-admin. If you can, then it is a theme issue. Login and dump that piece of code or fix it.

If you still can’t, now the work become a bit harder. Go to,

• wp-content/plugins and rename it to wp-content/plugins-old

• Now make another wp-plugins folder (don’t forget to set the permission as 755 only for this directory nor for files). And bring one plugin from “plugins-old” into the new wp-plugin folder.

• Now go to your website and check if it is working. If not, you found the culprit. If it works, then bring the next one.
• And repeat the process until you find the culprit.

Insufficient memory:

If the error is caused by insufficient memory, we can try to increase the memory limit, through wp-config.php or .htaccess.

define (‘WP_MEMORY_LIMIT’, ’64M’);

If you prefer to make the change through the .htaccess file, you can also. If you choose this path, you must modify the file by adding:

php_value memory_limit 64M

If still a problem this problem exist, you need to switch hosting to a higher plan. Consult to your web host to check the issue. If you have server administrators, you can ask them to investigate.

Permissions:

Verify that the files and folders have the correct permissions. Rules of thumb for WordPress:

Set all the directory permission as “755”

And File permission as “644”.

Logs:

It is also recommended that you verify the error logs. There you will probably find what file is causing the error and why.
