Try this one instead. Comet Chat
I have it on my 3.8 test site (link below)

Link I posted above shows it to work with 4.0 as well. To me, it was well worth the money.

I'll be happy to buy the pro version, but I do need to know you're going to be on top of fixes as the vbulletin versions get updated. The Lite version here doesn't work on my vBulletin 4.1.12 test site.

I like the features and how access to the chat is set by usergroup, which is exactly what I need, but it has to work obviously :)

well just seems like there is a lack of support...

Using vB 4.1.11. Enabled this mod and also set usergroup permissions. Friends Online showed up, listed no users, even though I know for sure there are users online. Slowed down my site and also prevented the vBshout shout box contents from displaying. Also, when you click "Settings" for this, does nothing and throws errors when you refresh the page. Disabling this plugin.

This mod killed my server.

Most every facebook style chat I've used has overloaded the server.. It's really not worth the headache.

Dont works for me ...

4.1.10

Seems it doesn't work with vBulletin 4.2.0.

Comet Chat is awesome! It works great and is very cheap. Has some nice features too that are useful apart from the chat. I won't be renewing my hosted chat next year with 123flashchat. Thanks for the heads up on Comet Chat! :up:

I was wondering if anyone even read my post...
