 * Having updated to the latest version of Wordfence (6.1.12). I got the following
   error messages – Unknown files in WordPress core. The files are listed below.
 * wp-includes/js/tinymce/wp-mce-help.php
    wp-includes/theme-compat/comments-popup.
   php wp-includes/js/tinymce/plugins/wpfullscreen/plugin.js wp-includes/js/tinymce/
   plugins/wpfullscreen/plugin.min.js wp-admin/js/wp-fullscreen.js wp-admin/js/wp-
   fullscreen.min.js
 * Is anyone else getting these same files flagged? If so, are they legitimate files?

 * There seems to be a lot of weird stuff going on with tinymce, that’s for sure.
   It’s an obnoxious pest, has been that way for years. My approach is to just do
   good backups, then delete all those files provided you don’t have any plugins
   running that appear to use them.
 * wp-fullscreen appears to be an artifact of a plugin.
 * One of the heinous problems with plugins is many of them don’t remove themselves
   when asked to. It’s a nightmare. Perhaps Wordfence will help since it points 
   out weirdness that was formerly somewhat hidden.
