Type in the path to your forums, then add
Code:
/vBChat.php?&do=main&nojoin=1
onto the end (sorry the link I gave earlier was wrong)
Edit: Ok, I don't know if that link will work.
Basically it boils down to this!
If you can get into vbchat quickly and the page loads ok, then copy the link thats in the address bar at that time (when you're in the chat).Then paste that link into the navbar area where the vbchat code is.
It's solved the problem for all of my users, and they're glad it's sorted.Let's be honest, nobody else is coming up with much.........
I hope it helps.
Cheers!
