Ok, so I figured out that another plugin NextGen gallery was causing the video to disappear when I activated the Enhanced header pro plugin.
It does play now everywhere but the sizing still doesn’t work right in the browser on a computer.
The size is right on the phone but now there is a giant black box under it that then has the header info. I don’t mind the info in a box under the video on mobile but is there now a way to shink that box and make it the actual background color of my website?
Thanks for your help!
