Can’t activate the full waf mode.

Can you run the troubleshooter script and paste the results here:
https://nintechnet.com/share/wp-check.txt

1. Rename this file to “wp-check.php”.
2. Upload it into your WordPress root folder.
3. Go to https://YOUR WEBSITE/wp-check.php
4. Delete it afterwards.

Here is:

I don’t see any error.
Can you confirm that you added the directive into the “Vhost Configuration > General> php.ini Override” section?

As an alternative, you can try this: https://openlitespeed.org/kb/change-php-settings-by-vhost-and-user/
Scroll down to “Override Global php.ini With Local php.ini through Virtual Host external app”.

Can you confirm that you added the directive into the “Vhost Configuration > General> php.ini Override” section? =>

php_admin_value open_basedir “/tmp:$VH_ROOT”
php_admin_value open_basedir “/tmp:$VH_ROOT”

—————————————–

Sorry, I did not get what was the point of that => https://openlitespeed.org/kb/change-php-settings-by-vhost-and-user/

You should have NinjaFirewall’s php_value auto_prepend_file... directive too, for instance:

If that still doesn’t work, try to replace the php_value ... directive with php_admin_value ....
