I am not sure if this is a bug or not, but I wanted to mention it to you. I have "debugging" turned on right now, so I am not sure if this happens to me because of debugging being on. Maybe this is "normal" behavior. Here's the problem.

Occasionally, I get an error message "JSON parse Error" when leaving a forum. It seems to happen after I have provided ratings, and then leaving this webpage. The error message is shown the attached picture.

This error message just shows itself briefly. I was able to capture this problem in a screen video. It's at the following URL:
