coppermine 1.3.2
an apostrophe in a user name causes database errors.
ie <noname00's group> as username.
It looks like it wasn't escaped. Can you enable magic quotes?
Not that this shouldn't be looked into in the code, but until it is addressed, magic quotes should help escape the apostrophe.
as far as I can remember this has been reported before (and fixed). Please search for a similar error report and the fix.
