SOLVED Editor (CKEditor) is missing in UI

[miE]

Hi all.
I have new installation of GetSimple and when try to edit a page, there is nothing that can be seen, just empty space, see http://fii.cz/zmvbam. Is there anything that needs to be set in order to get the editor working? Standard editor for html is ok.

SimpleCMS is 3.3.1

I use Chrome, but tested it with MS IE and Safari -- both works fine, just the Chrome troubles. Javascript console says: "Uncaught TypeError: Cannot read property 'options' of undefined" in ckeditor.js, line 51

Any idea?

Thanks in advance
