PROBLEM How to change the ckeditor skin?

[Connie]

Just a short note:

I updated to GS 3.3.9 from 3.3.9 today, overwriting /admin and index.php
the editor is broken in case you set any options in the gsconfig.php or use advanced options l/ custom config with a separate gs.js

only the plain vanilla editor out of the box is working at my installation (to be true, it's a clients' installation)

I hope this will be fixed soon.
