Describe the bug
Using Netlify as CMS - I am the user, not the developer. Developer unavailable at this time.
Trying to upload a .pdf to the Media section of our CMS. Keeps supplying me with an error message. No longer shows me the other pieces of media that were in there, like images and other pdfs.

To Reproduce

Expected behavior
I should be able to upload .pdfs or images. But keeps coming up with this error message (see screenshot below).
