For some reason periodically I get the following error displaying when trying to view a specific page:

-A forbidden parameter 'language' was passed to this page in the URL or a form.-

Clearing the site's data/cookies solves the issue for a short while and then it returns.

I understand the error is generated via 'Bootstrap' javascript files, but it doesn't explain the cause.

Can anyone shed any information on it, the cause, and above all how to fix it?

So this is a problem with cookies and not some GET parameter that is added to the URL ?

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window

If clearing cookies didn't help then it is possible that the cookies.sqlite file in the Firefox profile folder that stores the cookies got corrupted.

  • rename/remove cookies.sqlite (cookies.sqlite.old) and when present delete cookies.sqlite-shm and cookies.sqlite-wal in the Firefox profile folder with Firefox closed in case cookies.sqlite got corrupted.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Are you using a bookmark when you get this error or do you navigate starting at the home page ?

Navigating to the page.

I visit the page frequently, several times a day without issues, and without any from of pattern the error crops up. Here is the page: if it helps.
