This may be duplicate (reopen) of bug 774184?

I was able to edit all of these pages without error. Can you confirm if the problem is still there? It may have been bug 774184 or something else that is fixed since then.

I'm closing the bug right now, feel free to reopen it if you can reproduce.

That's strange as it works for me. Maybe is it a problem of rights?
/CC some people who may help us diagnose it.

Experiencing it right now on this page full of spelling mistakes :(
https://developer.mozilla.org/fr/docs/HTML/introduction

There is a link on the text "Another document with this slug already exists" which links to the same page with the anchor #id_slug. But it doesn't work on my version of the edit page.

I noticed this, also in the French articles.

The strange thing is that it's off and on. I noticed this a couple of hours ago, but it's not happening now.
