There's bugs everywhere; I can't log in half the time. I can't post half the time. For both I get the "OPPS security message of something gone wrong. Then the constant double posting. Then not being able to edit my own post.
Nothing personal.....buy why do you insist on running the beta software on a live forum. Run that on a VM not attached to the live forum. That way can identify and sort out any issues and report that to the hosting server software company...ie Xenforo. Do you get paid to run the BETA?
