getting rid of Media Module Message "Media Folder: Media Root"
A similar problem came up for me when upgrading a Drupal site to Drupal 7.53. I found that the "media folder" field suddenly started appearing on all images on the site.

What fixed it for me was hiding the media folder field from the file type generated by the file entity module (which makes files fieldable). Here are the steps to do that on your Drupal site:


Go to Home » Administration » Structure (admin/structure/file-types).
Click "Manage display" for the affected file type.
Change the label and format to "hidden" for the "Media folder" field and click save.
While you are at it, repeat steps 1 and 2 for all the file types on your site.
Clear your caches.
