 * Dear all,
 * we are using WordPress 4.3 and facing a problem with TinyMCE using Internet Explorer
   11.
 * It is not possible to:
    – Enter Text in the editor field (white screen) – The
   Button bar is not available anymore
 * Already tried all of this:
    1. Clear Browser Cache 2. Deactivate WP Cache Plugin,
   Delete Cache 3. Deactivate all WP Plugins 4. Download manually all WordPress 
   Files, Replace WordPress Files 5. Download newest TinyMCE Version, Replace Tiny
   MCE in WP Folder 6. Define( ‘CONCATENATE_SCRIPTS’, false ) in wp-config file 
   7. Switch Back to default Theme
 * We found out that it is a problem with the child theme and we found in the console
   of the internet explorer the following java script error:
 * SCRIPT5022: InvalidCharacterError
    Datei: tinymce.min.js, Zeile: 3, Spalte: 24308
 * Can anyone help to solve this issue?
 * Thanks in advance and all the best,
 * Steve
