ok kguske here are 7:37 am

OK. Let's focus on the error:

Code: SQL Error : 1046 No database selected SELECT * FROM nuke_bbconfig Line : 237 File : common.php

There is something about your Forum mods that changed how the database is connected. Please compress email the file:

modules/Forums/common.php

Also, check the site error log (or the error log in your nuke root folder) to see if a file was not located or could not be found.

There warnings also indicate something strange. But let's look at the common file first.
