The error you get indicates that one of the database tables that Groups creates – and requires – is missing. This table stores information about groups that the plugin handles and is essential.
This table should not be missing and must have been deleted by accident. Or if you have moved the site to another server, maybe the table was not imported.
I would recommend to recover from a backup to make sure your database is consistent.
Regarding the extension, yes, it requires Groups to be active. The table that is missing is essential for Groups, thus it is also essential for the extension to work properly.
Hi, thanks for the quick response,
I haven‘t moved the site or changed anything besides updating WP.
Will it be enough to recover the backup of just the plugin as there are a couple of customers and purchases and I don‘t know exactly when this issue occured.
