Hi @stormline…
It looks like one of your plugins is supplying an invalid file specification. What is expected is a path relative to the plugins folder. What is provided is a full URL.
Deactivate all plugins and the warnings should go away. Reactivate one plugin at a time, testing after each. When the warnings reappear, the last activated plugin is the cause.
I deactivated all plugins, but still have this error.
This domain migrated from cpanel to plesk. And after this happend this error.
@stormline I never use Plesk so I will recommend, approach their support team so they can help you with this problem in a proper way.
I have found the below links. Maybe you find them helpful.
Thanks!
The session.save_path setting in your php.ini file is not within the directories specified in the open_basedir setting. You may be able to correct this by adding the following line to your wp-config.php file immediately after the DB_NAME/DB_USER/etc MySQL settings:
ini_set('session.save_path', '/tmp');
If that doesn’t work, remove the above line and edit the open_basedir setting in the php.ini file. This setting requires some knowledge of your system, so you might want to ask your host to set it for you.
