This is a known issue (#113746:TinyMce: Edit Html source is blank in IE 11) in CMS-6R2 which won't be fixed for some reasons.  Try running IE in compatibility mode and see if that helps.

Hi Valdis,

Error: Object doesn't support property or method 'attachEvent'.

We get this error in tiny_mce_popup.js.

Have the same problem with IE 11. Works with original EPi6 R2 but after updating (to 6.1.379.1000) the HTML is blank.
Also got problem with tables.

Compatibility mode works but since we are working with an update for a customers site where hundreds of different editors will work on it there isn't a solution.

I had the same problem with IE 11. 

The solution worked for me was the below one.

To fix this compared to IE, there must be some changes in the JS file that you find here: themes / advanced / js / source_editor.js

Look at the function; onLoadInit ()

"tinymce.isGecko" prevents retrieving the data from the editor.

The following two lines must be moved at the start of the function:

1. document.getElementById('htmlSource').value = tinyMCEPopup.editor.getContent({source_view : true});

2. resizeInputs();
