-=DM=-,
Sometimes when you get disconnected, your name stays logged in. Which is a bugger in the free chat, cause you can't do anything about it.
But you can still log in using a different name
The errors you have, I had those as well. In my case they were the result of having gzip turned on the server as well as in vBulletin.
If gzip is already active on your website, then you don't need to set the options for it in vBulletin, so turn it off in the vB admin panel.
And that's another cool of doing it FWC. Thanks for sharing that
