Hi,
I solved this issue for my site already, but wanted to report it in case others encountered it.
The issue is similar to this one: YouTube video not displaying correctly on frontend
When embedding a youtube video on my site, the .mejs-container
element had a height of zero, meaning the video was showing as a blank white box.
I fixed this for myself simply by using the following element CSS:
$el .mejs-container {
height: 100%;
}
Thanks
