<input type="hidden" name="curl" value="%2F%2Fwww.mshastro.com%2F" /> what looks wierd..
let me check the / usually that caused it to not see .css and load most of the siite.. let me check.. I have to leave it blank
EDIT:
Ya I add the / instead of blank and the url changes to ubbthreads.php and I lose css etc.. looks more codeish then bad config.
with is blank the url link is
http://www.mshastro.com.. with / the url link is just ubbthreads.php.
the website references index.php and default doc
