I've been clicking for quite some time and I didn't get this error.

1. Which package you use? Is it one of predefined ones or you use some third party plugins as well? If yes please try without these plugins.
2. Are you using any Chrome plugins? If yes, could you try without them?
3. Have you made any core code modifications in CKEditor?
4. Which operating system you use?
5. Could you send us your build-config.js and page where you have CKEditor configured - provided that you are using some non-standard settings or plugins.

[Alex]

Yeah It is pretty random, I didn't notice any consistency yet but I will keep trying.

1) I use standard package and I do use plugins, will send you more details today, one of the plugins is a Roxy file manager.

2) I do use chrome plugins, will disable and let you know if it helped.

3) No core modifications done

4) Windows 7

5) Will send the js today, the only plugins I use is jquery 1.7.2 and jquery UI 1.8 widgets.

Thanks

1) I have uploaded build-config

2) I have disabled all my chrome plugins but I still get the error.

Also don't no if it related to the same issue but in IE11 I get the following error when I just open ck editor with text being populated via jquery ajax:

SCRIPT70: Permission denied

File: site.aspx, Line: 54, Column: 375

Nothing is crashed, ckeditor continue to work fine.

Thanks

I think I have found a solution,
After I have removed the first CKEDITOR.instancestxtEditor?.setData("");
I could not reproduce anymore the error in chrome and IE11
Still trying...

I understand now that I can't call setData twice?

I still need to clean the content before I load a new one, any good possible solutions?

function LoadHtml(ContentID) {
    ShowPopup();    
    CKEDITOR.instances['txtEditor'].setData("");
    $('div').append(AnimationLoad);

    PostAsyncAjax("Edit",
        { 'ContentID': ContentID},
        function (data) {
            var ckData = data.d;
            CKEDITOR.instances['txtEditor'].setData(ckData.HtmlContent);
            $('#AnimationLoad').remove();
        }
    );
}

If this is setData called twice issue that this is a duplicate of #10501. Yes there is bug with it.

Please have a look at workarounds mentioned there. If they don't suit you than perhaps below workaround might be something you need.

var editor = CKEDITOR.replace('someName', { });
editor.on( 'instanceReady', function(){               
                editor.element.$.value = 'Hello';
                editor.setData( 'Hello', function(){
                    CKEDITOR.myDataLoaded = true;
                });
               
               
                if( CKEDITOR.myDataLoaded )
                    editor.setData( 'Hello' );
                else {
                    var interval = window.setInterval( function() {
                        if( CKEDITOR.myDataLoaded ){
                            editor.setData( 'Hello' );
                            window.clearInterval( interval );
                        }   
                    }, 200);
                }   
            });

DUP of #10501.
