10030	"IE8 ""Unspecified Error ckeditor.js, line 63 character 296"" on CKEditor 4 load"	Tony Payne	Artur Delura	"I updated from CKEditor 3 to 4, updated the custom config, plugins etc, and everything seems to work ok, except that sometimes when the editor instance loads I get this error ""Unspecified Error ckeditor.js, line 63 character 296"". The section of ckeditor.js on line 63 that is highlighted by IE8 debugger is:
{{{
return new CKEDITOR.dom.element(this.$.activeElement)
}}}

This is sporadic, doesn't happen every time, and never used to happen with CKEditor3.  I can load a page and editor content loads correctly, save the content, reload the page, and then I get the error, even though the content to include in the textarea has not changed (it's stored in an SQL table).

As far as I am aware this is only happening in IE8 (I am running XP Pro with SP3).  I can't replicate on FF or Chrome.

Attached is:

(a) The code on the page that activates the editor

(b) The editor content that is being loaded

(c) The custom config.
