IE 7 issue loading editor - 'items' is null or not an object

I get an error when I try to load CKEditor in IE7, it works fine in Chrome/Firefox. I am using the latest version of the DLL for ASP.NET, and I am using the latest version of the .js file from version 4.*. The error I get says:

'items' is null or not an object

Line: 634

Char:364

This appears to be in the main.js file for the editor code. The control does not even load at all on the page, which remains blank. Has anyone else encountered this?

I think that the latests

I think that the latests versions of CKEditor 4 are no longer compatible with IE7, so if you want to use a browser so old you have to also use an older version of CKEditor, not the latest one.

Just reproduced this on IE8

Just reproduced this on IE8 with CKEditor 4.3.3:

Webpage error details

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET4.0C; .NET4.0E)
Timestamp: Mon, 24 Mar 2014 22:07:59 UTC

Message: 'items' is null or not an object
Line: 672
Char: 364
Code: 0

In my case, the cause was an incorrectly formatted config file:

CKEDITOR.editorConfig = function( config ) {
    config.toolbar = [
        { name: 'Maximize', items: [ 'Maximize' ] },
       { name: 'Source', items: [ 'Source' ] },      // BAD!!! Comma prohibited on last item.
   ];

};

Removing the comma (that is tolerated by most modern browsers) fixed the issue for IE8. I can't test on IE7, though.

Hope this helps someone. Thanks for an incredible tool.
