Hello. When I try to add Tags, a dialog box pops up but I get this message: 0 Class 'acymailing' not found. I looked through the plugins and those that could be an issue such as the old Icagenda and Joomla Content plugin were not published. Also, checked database integrity, all was good. Any assistance is appreciated.
AcyMailing Enterprise : 5.10.18
PHP: 7.2.34 (I know, time to update)
