After the last update the inline HTML editor does not work. All I get is shown in the attached image. Any ideas?

Thanks!

 

The popup HTML editor also does not work. Only the editing in HTML source seems possible.

Tried to clear the browser cache?
Tried with a different browser?
Tried to clean the asset cache?
