Using Drupal 7, our media browser stopped working on a clients site. They are using the media browser to upload an image to a product, but when they click upload they get a blank media browser modal. When we heard about the bug, we went in as an admin to try to upload, and we have the same bug. This was working for ever, as the site has been live for months, this is a new bug.

In the JS console receiving the error:

Refused to display XXX in a frame because it set ‘X-Frame-Options’ to ‘deny’.

Does anyone know the fix for Drupal 7 Media Browser would be regarding x-frame options?

Edit: Went to our dev environment which live is a clone of, and the media browser works fine, so it’s an environment thing I am assuming. We have adding no new modules, and have not updated major versions in months. We are hosting on AWS.
