ACP gone

[400d]

Hi to all of you. I have a big problem on my forum. I've tried everything that I could find to solve this problem, but nothing worked.

So let me explain how it all started. I came to a thread here on this forum on how to hide ip addresses from moderators: http://community.mybb.com/thread-145588.html

So I followed this procedure 'in ACP goto Users & Groups >> Groups >> Moderators >> Miscellaneous >> uncheck Can view IP addresses on who's online?'

after I got back to my forum from ACP I completely lost all administrator privileges. Can't login to ACP anymore. I lost Admin CP icon on top of the forum.

My nickname is still green colored (administrator color) and when I go to Forum Team my nickname is still marked as an administrator.

Of course I have tried with this query

UPDATE `mybb_users` SET usergroup='4' WHERE uid='X' 

but it didn't work.

when I go to table mybb_users - everything is set up as it should be - I'm in the usergroup no. 4 which is Administrators.

But still can't log to ACP.

Does anyone have any idea on how to solve this?
