MyBB Community Forums

Hi Guys!
I've a forum installed with latest myBB version. A few months ago I updated my forum from an old previous version. But after the upgrade, my mycodes and even html codes stopped working in threads and replies. Screenshot is given below. Kindly help how to fix this problem.

Hello,
could you try reverting your codebuttons template to the default style? I'm not sure if that's the issue in this case, but it's worth a try.
