Fatal error: require_once(): Failed opening required 'includes/utility/plugin-base.php'

Hello! After updating X and Cornerstone one month ago I get this error message on trying to open the Site https://www.vorsorge-pachernegg.at in the Browser:

Warning: require_once(includes/utility/plugin-base.php): failed to open stream: No such file or directory in /www/htdocs/w013e31f/vorsorge-pachernegg.at/wp-content/plugins/cornerstone/cornerstone.php on line 18

Fatal error: require_once(): Failed opening required ‘includes/utility/plugin-base.php’ (include_path=’.:/usr/share/php:…’) in /www/htdocs/w013e31f/vorsorge-pachernegg.at/wp-content/plugins/cornerstone/cornerstone.php on line 18

The same message appears if I try to login to the wordpress-backend.

I restored various backups (newer and older ones) but the error is still here. This ist strange to me, maybe You can tell me the mistake I make…

Thank You in advance for Your help!

Hi there,

The update might not be successful as some files might be corrupted.

Please login through FTP the go to wp-content/plugins then delete the current cornerstone directory that is in there.

Once deleted, log back in to the admin and Cornerstone should be automatically installed and activated again.

Let us know how it goes.

Thank You. If I delete the cornerstone directory, I cannot login to wordpress-admin anymore, I get the mentioned error message. But I restored the cornerstone and the x directory from my backup and it works! I just check the site if there are some other problems, but for now it looks good.
