This error occurred after an attempt to install the latest version update of Acymailing Starter 7.4.0. I have no access to anything in the admin panel. So database fix is no option. Thank you
Can you please try to visit the following URL in your browser
That should fix the issue.
Unfortunately the error stays the same,
can i do sth trought phpmyadmin? Drop settings column somewhere?
Unfortunately i removed all of acymailing stuff by phpmyadmin and ftp and started all over...
Is it working for you now?
yes, so a clean install of acymailing, restore data from DB, probably because there used to be a Acymailing 5 Essentials subscription, now a 7 starter update... (could not restore mailing lists by sql, did this manually...)
