The visual editor don't work any more on this page of fr.wikiversity ( https://fr.wikiversity.org/wiki/Recherche:Imagine_un_monde/Innovations ) and only on this page or other pages if copy paste de code like on my draft page ( https://fr.wikiversity.org/wiki/Utilisateur:Lionel_Scheepmans/Brouillon ), where the bug was translated.
When the loading bar arrive to the end, the web page stay blocked and the situation happen both with firefox than Chromium on my desktop running with linux mint.
Probably some thing on the code is not supported by the VE but what ?
An other symptom of the bug on my draft page is that when I click on a link present on the menu up to the page just on right of the taklpage link, the visual Editor start to be installed automatically.
I've tried to revert my last edit but no way... Only if I come back before the copy past on my draft page the bug disappear.
It's a bite annoying because I have to finish to edit this page for Friday and I need for it to use the visual editor.
Editing with code still work, but that's much more uncomfortable for me.
Oh, I just met the same bug on this page to : https://fr.wikiversity.org/wiki/Recherche:Imagine_un_monde/Mouvement_Wikim%C3%A9dia where I had switch a part of the text coming from the page https://fr.wikiversity.org/wiki/Recherche:Imagine_un_monde/Innovations.
Maybe a clue to fix the bug ?
