Re: Cant view user pages.
You got the Dashboard working, I see.
The "My Profile" link within the dashboard now works too!
Clicking my name on the actual ad does not work.
I'd walk through the install guide again. Make sure all the files are in the right place and have the correct permissions... bet ya missed something.
*edit: Did you see this post?

A similar problem was caused by permlink settings.
