CKEditor doesn't work after updating I've updated a drupal website to the latest 7.x version, and CKEditor stopped working. I had it originally getting //cdn.ckeditor.com/4.5.4/full-all, I've updated to //cdn.ckeditor.com/4.13.0/full but no luck. I've tried to remove and reinstall the module, clear the website and browser caches, etc. I've also uploaded the version and used it from the local disk rather than the CDN (in case there were network issues with the CDN site, but I didn't see any errors).

I'm short of ideas. Has anyone experienced this and has some more ideas for me to try?
Should anyone be interested, updating to the latest core (7.69) seems to have restored the CKEditor functionality.
