XF 1.4 Internal Server Error creating post with BB code

[vbuser]

I was copy-and-pasting a long post with BB code on my about me and saved no problems. I went back to edit and tried to save and got error message. Also error message when toggling BB Code Editor button. No error shows up in my Cpanel error log.

Note: This is my test forum. I do have mod security but something shows in the error log when this happens.

You will need to check the server error logs to see what triggered the error.

Are you able to make the same post in the test forum here and reproduce the error?
