Ok. So I upgraded to 2.2.14 and noticed today that two users from two different sites belonging to another reseller was shown under one of the sites email&users for one site belonging to another reseller. This is on my testsystem which I use to mirror my main server before any upgrade. Why is this, anyone have an idea what may have gone wrong? These two "extra " users under that site display as having admin, but when I click any of those two with my administrations account I get a message that I dont have priviledges to edit these users. The users display properly under their normal site and are editable there. All sites work properly on the filesystem and I dont see that any users would be associated with the wrong site "on filesystem" level. I'm proceeding to upgrade to 2.2.15 to see if this bug/weirdness gets solved on this system.
Additionally. It's not possible to add new users to that site for some reason, simply gives me "there's already an administrator" although I havent click the admin box on the new user.. weirdness.
Looks as your database is corrupted. This corruption can not happen trough a update and its not a bug in the siftware itself. It seems that the relations for one or more sites are broken, so that a user is listed under the wrong site.
