CKEditor hangs with hourglass when trying to edit a page

I have a new install of XWiki with CKEditor 1.16.
I cannot edit a page using CKEditor 1.16 as it just hangs with the hourglass when I hit ‘edit’
I installed using the extensions manager.

I get the following javascript errors which appear related

    resourcePicker.bundle.min.js Failed to load resource: the server responded with a status of 404 (Not Found)

Hello, I have the same error about requirejs: Javascript issue on xwiki 8.4.4 and FF 52.3.0
… but didn’t found the cause, sorry

Thanks PBas, I read your post and then tried a different browser.
So its on Chrome it fails but on Firefox 55 it works fine.
So the problem is the browser not the extension?

Did you try to clear your browser’s cache and reload?

On my side it’s failed on FF and working well on chrome.

If I refresh with Ctrl+F5, sometime CKEditor/require.js loading well but only one time on 10 :-/

Wow, that simple and it works now on Chrome and on Firefox.
