Too few arguments to function CommonPanel_Aps_Model::logAction(), 2 passed in /opt/psa/admin/plib/modules/wp-toolkit/library/Service/Instance/InstanceUpdate.php on line 113 and exactly 4 expected
As we have found, an issue affects websites, installed using Plesk applications catalog (also known as APS applications catalog). We plan to deliver an update that will fix it within a few days. I apologize for the inconvenience.
I glad to inform you that an update of WordPress Toolkit 5.1.1 has been published a few minutes ago. An issue with updating websites installed using Applications catalog now considered as fixed. I hope it will work for you. Feel free to post here if it's not, we will be waiting for your feedback.
