I have 2 XenForo forums on my dedicated server and each have Nginx error pages set up for every error code. Problem is, when an XF error should display (eg. a user doesnt have access to view a node), instead of the XenForo Login page displaying, i get my Nginx 403 error page. On my other forum, when i have the board inactive, the page displays a 503 error for users who aren't logged in. Any idea's whats happening?
