The file could not be found, i looked up the upgrade ressources, this file wasnt present there as well, whats wrong here? 

Strange, have no issues.

This is 4.1 yeah?

See attached the ckeditor folder - place the folder inside /applications/core/interface. Please let me know when you have downloaded it so I can remove it from this post.

ckeditor.zip

Got it, thanks, will try, but you're missing also his file "plugins/widgets/plugin.js"

I just checked every dev version I have, none of them have plugin.js - this would be generated dynamically I could only assume.

(Possibly read/write issues somewhere?)

Support ticket this one.

Uhm. Seems like there was an issue on the upgrading process, maybe a read write issue as you said.

After replacing it now, it seems to work fine.

Thanks.
