    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
