I've got myself a bit of a problem after upgrading from 1.8.0 to 1.8.2.
Since upgrading I can't delete any users or groups. If I try to delete one I get the message "click here to confirm your action", then when I click the button I get a 404 file not found error.
The reason for this is that the URL it can't find is:
Replacing the errant "/" with a "?" just brings me back to the "please confirm" page.
Actually, I tell a lie, I just tried deleting a few other things, basically, I can't delete anything. It gives the same sort of error (tiki-file_galleries.php/offset=... when trying to delete a file gallery for example).
