Database Quiry Error !!! Please help asap !!

I tried to install new copy  of dolphin in sub-domain and now my actual current site is Showing a Database quiry Error!!!!

Idont know why or how to fix please help Boonex users ???

You will need to provide the error. We cannot assist without it.

You most likely better provide a step by step guide for us as to how you installed this sub domain copy so we can try to determine if you did something wrong there.

only thing i can think of is that you used the same DB.. for your new install in that case there isn't much help without a db backup.
