Double Posting and Redirecting Messages?

[King Justice]

Hello..

First off, I have redirect messages etc DISABLED because I hate that...

I just transferred my forum to a new server via hard drive writing to the new hard drive on the new server..

So now the forum is having conflicts..

Randomly after posts, redirect messages appear..

And worst of all, for some reason, quick reply ajax sometimes causes double posts!

How can I fix these issues?
