Hmm, while checking the error log i’ve found a few errors about the third party plugin but also found this error:
PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 458752 bytes) in /var/www/vhosts/mydomain.com/httpdocs/wp-includes/class-wp-scripts.php on line 473′, referer: https://mydomain.com/wp-admin/plugins.php
So i’ve tried to disable a different plugin and add page works again, so looks like it’s not any specific plugin but a memory limit.
Thank you, i’ve found the error log and the offending plugin. I’ve deactivated it and add page works. I’ve tried to activate it again and upgrade but add page function still fires the error. What to do in this case? Write to the developer?
