Sure, the line is up again in the template (
http://www.pinkfloydfan.net/forums/show.php?pg=test), which looks exactly like the whoareyou template, except that everyone could technically see it.
I still get a blank page with only "mySQL error:No Database Selected" on it.
I also double-checked the default webqueries and they seem ok, just like you said.
I'm really clueless about this. The weird thing is that the first time I installed WebTemplates, just after installing vB for the first time and testing it for a while, it seemed to work fine...
Thanks anyway for your help and support!
