When I try to post a new thread at https://ubuntuforums.org/forumdisplay.php?f=331 (Ubuntu general help section), the 403 Forbidden error was occurred. Attached here with the screenshot. Please fix the issue.
I solved this issue by making the thread shorter. I suggest that, when user try to post a thread, and the length of the post exceed the limits, an error should be shown, and user should be given chance to make the post shorter.
