Reporting a JavaScript bug
When you encounter a bug that may be related to JavaScript, do your best to identify error messages and copy them into the bug report.

It's especially important to provide all the information you have, because even the system administrators will have zero access to any error log. If you are unsure whether a feature you are using is based on JavaScript, try disabling JavaScript.
