I have just installed MYBB and have accidentally deleted my username.
Is there anyway I can rejoin and claim back full admin rights?
If you have just installed it and done nothing else, it might be worth just re-installing MyBB again. If you have made changes, just post here again and I'll dig out the SQL code needed.
I have added some mods, a new theme and merged all data from PHPBB3
I don't know how to run a query in phpMyAdmin
