In Classipress, I used the "Block" editing tool to embed a youtube video on a page. The block tool has both a YouTube embedding button and a generic "video" embedding button. I tried both and had the problem with both. The block YouTube embedding button opened and asked for me to "Paste a link to the content you want to display on your site." I entered the URL and clicked "embed." The YouTube vide appeared on the screen without a problem. I then "updated" the page. The YouTube video remained on the screen. More importantly, the YouTube red arrow button played the video successfully when clicked. See image below, "Snip draft 1." By the way this is a video I created and uploaded to YouTube and granted permission for the video to be embedded.
Here's the problem. The video does NOT display when I visit the site. Instead, the video is gone and only the URL address appears in its stead. See image below, "Snip final 1." How do I embed the video?
