Can't use my "Admin Tools" button

[asas]

Hello guys.

I searched for a similar problem but found none:

Many things in my gallery are not working as relating to login issues, but the most important of all is the "admin tools" button which doesn't work. I just get the error:  There was an error while processing a database query


Other problems I am getting include the following: ( I am using PHPBB2)

-If I log in from the forum, I am still not logged in from the forums and vise versa.
-(possibly due to a cookie problem) when I log out, it doesnt work at all at times. Whether I log out from the forums or the gallery.
-Only sometimes, clicking on "Admin Mode" does nothing. Just like refreshes the same page, and bring me back to the same user mode.



Thank You
