"Incorrect server response" on upload

[timinformatica]

I leave this comment for future use, if someone else search for the same problem:

I have updated CKeditor to the latest version 4.10
Everything works fine but image/file upload is not working any more. When I click on upload, a popup returns that says "Incorrect server response".
I try to update kcfinder to this 3.20 version but the issue still persist.
For others in my situation the fastest resolution was to add in config.js of ckeditor, this line:

config.filebrowserUploadMethod = 'form';
