A user reported that in her course, she was not able to upload video files into the Share File widget. I was able to replicate this issue.

When trying to upload the video files, the subpage just disappears. However, I was able to upload images and PDF files. Only video files didn't work (mp4 format).

Tested and confirmed this on Chrome, Firefox, IE, Safari, and Android Browser. It happened throughout the course. Oddly, I was able to upload video files into the Share File widget on another course. This error happened only on this course.
