Well I just tried to make a post in a thread with this text.


I got this:


I thought it was an error of some sort so I posted "test test" but that worked fine. So I edited post to "lololololol" That worked. Then I edited my post back to that first code and got the same display. I think my code could be interfering with one of the mybb plugin or triggering a security plugin causing an error to be thrown. I've tested in multiple threads and am 100% sure its something in the code not just a random 1 off error.
