 > We are on Siteground and user SG Supercache. I cleared cache several
 times to no avail. Even after I deleted /wp-includes/js/backbone.min.js,
 the file was still loading. Just created a ticket with Siteground to clear
 this file from server cache. Has this solution consistently work for you?

 So far, yes - the solution is working...

 But the specific files, plugins, includes etc. could be different per
 user/dev. I'm not a WP architect or moderator, but I would recommend the
 following to anyone experiencing similar issues.

 attempt to recreate problem in different browsers.
 use the inspector -> console - locate problem files and their specific
 paths (right click on file name - copy link location, paste in new window,
 so you can use the path to dump from cache later - (CDN cache or a WP
 cache plugin etc.)).
 it seems like many people are having problems related to a cached
 javascript file in a plugin (or include files), whether it's Media Library
 or Backbone or something else. Even if it's unrelated, a JS error will
 cause other stuff to break (preaching to the choir here probably).
 If you're using a service to cache files, you may have to provide the
 specific path of the file you need to purge from your cache. In my case,
 I've been using cloudflare a lot for this (custom purge).

 Re: cache - The more I learn about cache, the less I understand about
 cache
 So, after the server cache is purged, and the CDN cache is purged, we
 still have the browser cache to purge. All the caches will store files and
 paths you're trying get to read directly from your server environment. So,
 purge everything so you're getting a fresh clean download. It sounds
 scary, but it might help. Try using a top down approach:
 1. purge CDN cache
 2. purge server cache
 3. purge any WP cache plug ins
 4. purge browser caches - You don't have to delete the browsing history or
 cookies - just cached images + files (browser might log you out otherwise)

 Maybe there is a bug somewhere, but I haven't identified a REAL BUG >> If
 I'm wrong, just ignore the above and accept my apologies :)
