I'm not sure the best title for this. But once I'm logged in I cannot access my site the same way anymore. For example if the address is www. site.com/forum/ once logged in it now has to be www.site.com/forum/index.php?forums I think this just started happening after installing arrow chat but I'm not sure. This makes it so the link in the admin cp doesn't work because www.site.com/forum/index.php is invalid too. Any idea what would cause this or how to fix it?
