Incompatible browsers

If you use a browser which is a lower version of the browsers listed in the table above or your browser does not appear in the table, CKEditor will work with limited features or will not work at all. You will only see the editing area where you can write in the HTML code. The toolbar will not appear at all.

If you want to work with all of CKEditor features install one of the compatible browsers and than run the editor.
