MyBB Community Forums

Something I noticed. The query for the two cases is different.

In the thread by Oded, it says this
Query: SELECT * FROM mybb_sessions WHERE sid='0' AND ip='xxx.xxx.xxx.xx'

In my case, it says this
Query: DELETE FROM mybb_sessions WHERE ip='12.72.153.72' LIMIT 1

Your going to need to tell your friend that he needs to repair the database via phpMyAdmin or via a MySQL terminal.
