Thread:Project:Support desk/Portal creation error

Site In the link you see what happens. I don't know why, I've followed the tutorial to create a portal. But it doesn't work. Maybe it's my fault, since I've put the lines: define( "NS_PORTAL", 100 ); define( "NS_PORTAL_TALK", 101 ); $wgExtraNamespaces[NS_PORTAL] = "Portal"; $wgExtraNamespaces[NS_PORTAL_TALK] = "Portal_talk"; only after: Is that my fault? What can i do to make it works?
