A few weeks ago the Submit button in this forum stopped to work for me in about 50% of the cases. Then I copy my answer or comment, reload the page, paste my answer an then submitting works. (Windows 10, Firefox)
During the reload I must wait until all elements are loaded. If I press the "Answer" or "Comment" button too early, I cannot paste my message and have to reaload the page again.
  1. Is this problem known already?
  2. How can I find out, if a corresponding question was asked before? I've tried a bunch of keywords in the search field: meta, forum's interface, bug report, submit etc. After typing each new keyword, I have to select the order "Date asked - newest to oldest" again. This is was time-consuming and not successful. For searchs in the forum I usually ask Google, because I get better matches than using the internal search field.

I normally use PaleMoon with dark userstyles and I bludgeon the web with as much ad/script/element blocking as I can get away with to debloat and declutter frequently-used pages.
Attempts to run ad/script blocking on the site would routinely wind up with me having to log out and purge cookies & cache to stop the "empty post body" error described above. A few months ago, something changed and the editor simply stopped loading (a webcomponents support issue?). Since then, I've been using a virgin Firefox profile for the forum alone, and treating the site like a carton of eggs.
I haven't bothered trying to make a userstyle that works with the editor correctly. If DarkReader works, maybe I'll give that a whirl. On the bright (ha ha) side, at least I don't have cataracts anymore, so the site style at least isn't blinding.

As far as we can tell, the failure of the Submit button occurs if you display another Question before you Submit the current one. Only the Question you most recently displayed may be submitted for. This has been reported to Mathworks.
The workaround is what you found, copy, refresh, paste, submit.

Thanks your this useful answer.
It would be useful to have a "Known bugs" page, such that not all users have to search for a solution by their own. In the past I had difficulties caused by the OS, the browser, a darkmode add-on for FireFox and the network speed, but in most cases a strange behaviour was caused by the server. It is time-consuming for users to test, if the problem is on the client or server side.
I think, it is more efficient, if such a thread containing known bugs is created and updated by MathWorks, not by a user like me. Most likely if alink to this thread is provided at a prominent location (together with the FAQ, Terms of Use und Guidelines of the forum), the traffic caused by bug reports is reduced.

Jan, try again. The developer put in a potential fix today. Let us know if it works or fails.
