Comment (by needle):

 I've come across the same reference to the non-existent file when using
 `wp_editor()` in a theme to provide TinyMCE for the comment textarea.
 Perhaps the following might help untangle what happens in cases like this.

 It took me a while to understand what was going on, because two identical
 installs exhibited different behaviours; ie, one loaded TinyMCE correctly,
 the other failed and referenced the non-existent file `wp-
 includes/js/tinymce/themes/simple/editor_template.js`.

 It turned out that `wp_default_editor()` (called from line 555 of `class-
 wp-editor.php`) was returning the "currently active" editor in the post
 edit screen. In one install, my user had selected the HTML tab to edit a
 post, and therefore TinyMCE never loaded for the `wp_editor()` instance in
 the comment textarea. Nor was there a fallback because I had set
 `'quicktags' => false`.

 So, if you've set `'quicktags' => false` in your `wp_editor()` settings
 for your metabox and you've got `HTML` as your currently active editor for
 the post, you might well see TinyMCE fail to load. My solution was to use
 the `wp_default_editor` filter to return `'tinymce'` for my instance.

 Hope that helps.
