I'm having trouble getting this to work. I installed it and now no replies can be added at all -- users just keep getting taken back to the preview message screen. It is also showing every reply on the thread, not just the new ones. The "continue" button just takes them back to the same preview screen, over and over, so no posts get posted.
Any thoughts on what I did wrong?
I went back and did it all a second time to see if I missed a step, but the same thing happened.
