I'm still having the same issue. When I'm in the Gallery:
http://clevelandpaintball.com/gallery/index.php and I click on the Private Messages link in the upper right corner, the style is all messed up. For some reason, the Private Message link is:
http://clevelandpaintball.com/gallery/private.php instead of
http://clevelandpaintball.com/forums/private.php
I've already checked the Navbar Replacements and
private.php is listed. For the heck of it, I also added private.php to the Header Replacements too.
