Can't edit website after version upgrade

Hello

I recently upgraded all my websites to 8.5.17.
It works fine on all my websites except one.

On montres-bonnes-affaires.com, I can’t edit pages anymore.

Any idea what I should do ?

Did you clear the cache after the upgrade?
Are there any javascript errors on the page when you are in edit mode?
Are there any errors in the Dashboard → Reports → Logs?

Thank you for your help hutman ! I appreciate that !

I have just clear the cache and it doesn’t help.
There is no error in the page or in the Reports < Logs…

Any other ideas … ?

There’s likely an error reported in the browser’s JavaScript console. Open it on the browser and then click on the edit button. Some error in JavaScript can block the other scripts from executing which can prevent you from editing your site.

Like Myq said it’s likely a javascript error, if you open your browser’s developer tools and click on the Console tab you should be able to see if there are any errors when you go into edit mode.

Dear @Myq and @hutman, thank you for your help, I really appreciate that.

I did what you asked and I have indeed some errors in my browser Console tab :

But this code is an unknown foreign language for me…
Any idea on how to fix the issue ?

As it may help : I use Elemental theme, no add-ons installed, and I have already clear the cache of both the site and my browser.

Thank you all for your help

It looks like the beginning part of the javascript errors is missing here, can you check and see if there is more?

Sorry, here is the full code

Anyone has an idea ?

Do you think updating the C5 version to 9.x.x may help ?

So after much trouble, and the precious help of @mnakalay, the website is now under 9.3.4

But I still have this bloody error which deters me from updating the website :

Anyone has an idea ?

Does this happen on every page or just certain pages. If you create a new page, do you also see it?

On all pages, even a new one
