I have been attempting to embed a video in a course on PowerDMS. Each time I create the rich text with the embed code and go to preview, the video shows in the screen as it normally would. However it will not save. When I click save, I get this message:

I have tried multiple computers trying to embed the video but have the same message come up saying changes could not be saved. Can anyone provide some insight as to why this could be happening?
Thanks in advance.
