An appropriate representation of the requested resource /forum.php could not be found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Couldn't update this until I changed my browser (using IE now :/). So, basically this site gives me white page with the text above when I enter here with firefox and if I delete cache/clear history then I can reload to see the page. But, if I use any link in this site, it will happen again. :P /repeat.
* Does happen at one other site too
* Works on other sites so far
