You need newer CKEditor for uploads to work.

You have written you are using CKEditor for ASP.NET 3.6.6.2. Please bear in mind that you can update client side version to CKEditor 4.5.6.

Download CKEditor 3.6.6.2 for ASP.NET, unpack, go to your-ckeditor-aspnet-3.6.6.2-folder\_Samples and delete \ckeditor\ directory. Download FULL package for CKEditor 4.5.6 and extract it to \ckeditor\ directory. Next copy \ckeditor\ directory to your-ckeditor-aspnet-3.6.6.2-folder\_Samples.

In CKEditor 4.1 we have introduced ACF. You can read about it here: ​http://ckeditor.com/blog/Upgrading-to-CKEditor-4.1

​http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-extraAllowedContent

If you plan to use content filter please note that CKEditor for ASP.NET 4.x is still under construction and to change ACF settings you would have to use config.js as it can’t be done from control level.

NOTE: IE11 is supported from CKEditor 4.3
