Upload/browse files buttons disappeared in Product Images Tab

[AgreenWSI]

Upload/browse files buttons disappeared in Product Images Tab, and no images can be seen on the backend for products that we know for sure have images uploaded. We can view the images from the frontend, but not the backend, and as I stated, the upload and browse file buttons are not there. Below is a print screen image. No patches or updates have been made recently.

I've had this before when we've accidentally missed deploying a couple of the JS files, or when the permissions are incorrect on the media folder. Have you checked these two?

Are there any errors in the browser console when you load the page?
