I have been trying add video files to my slides and keep getting an Access Denied error when trying to test the lesson. I'm using the Opigno Video App and the videos are playing fine from the videos tab. I have disabled the HTML text format so the editor will output the iframe to hold the vid yet I'm still getting Access Denied (and the iframe shows the Opigno interface rather than the video). I have enabled permissions on the videos so they cam be viewed by any user level. Anyone able to shed some light on this?
