I have never had this problem and have been using the same settings on one of my websites as I have for all the others. My video will not loop. I choose loop (and had tried other toggles in the content area of the video layer settings), I save my slider video, then refresh and it didn't save. I deactivated every plugin, that did not remedy the problem. I even tried to add the video multiple times to make it appear its looping and it won't. I have made 4 different sliders as well. Can you help or tell me how I contact Revolution Slider to help?
