 * I just upgraded from 1.3 and now I’m getting errors on pages that use the plugin.
 * > `Call to undefined function just_custom_media_url()`
 * Has this been deprecated and replaced with a different function? What do I need
   to update in the code? I was not the one originally responsible for creating 
   the template, just coming in after the fact.
