I installed https://maurisweb.ru/ addon and after expired trial when I try to access admin addon manager page I get -Service unavailable- error. How to disable the addon from database because maurisweb support doesn’t reply and I need urgent access.
In this case seems like the only way is to completely delete this entry from the table.
Make the back up of this table (cscart_addons) and execute the following query:
DELETE FROM cscart_addons WHERE addon = 'mariusweb_addon_manager';
