When you say 'it loaded another page', what did it load?
After joining your server, type motdfile in server and game console.
If it says something different, you may have a conflicting mod or setting. Make sure you don't have your Source /settings/server.cfg set for a motdfile parameter..
Also, I've no idea if Source's webkit handles redirects. (Not a limitation of ULX, we use Gmod's(Source's) webkit)
The link you gave for the forum actually redirects to a totally separate URL.
Grab _that_ url and paste it directly in if the above motdfile parameter doesn't work.
Also, yes it's got a menu, Xgui is now included. (claps/applause)
Stickly man, Megiddo, can "ulx menu" not open the xgui menu anymore? Has the menu startup changed to "xgui"?
What error are you getting when you type "ulx menu".
Check both server and game console for error.
