When I am chaning subscriptions status "Update the status of the webspace" task fails with error:
Connection problem: Please check the PPA system log /usr/local/ppa/log/plesk.log for details.
The following error is shown in
PHP Warning: First parameter must either be an object or the name of an existing class; File: /usr/local/psa/admin/plib/registry/EventListener/OnstatusChange.php, Line: 123
The issue is caused by custom Parallels Plesk Panel Extension
