I'm trying to upload video or image using the new rich content editor but there's something wrong.
Firstly I couldn't find the "upload/record media" button as it does not exist I can see the only two options ( Course Media and User Media ).
and if I upload an image this error message "Something went wrong, try again after refreshing the page" appears
the only way I could upload an image through creating a new course and new module.

secondly, I would like to know if there's an option to make the video play just one time for the student ( I mean that I don't want the student to have the ability to play the video more than once )
