 * Check your Nginx config. It may be blocking some files. In my case the server
   was blocking **TinyMCE**, and I worked around it by adding this to my theme to
   avoid the `?wp-mce-*` query string that some WAFs block:
 * `// TinyMCE: avoid ?wp-mce-**** query that some WAFs block add_filter('tiny_mce_before_init',
   function ($init) { $init['cache_suffix'] = 'v=1'; return $init; });`
 * This solved it for me.
