[Plugin: My Youtube Playlist] Coding showing, not videos

I recently started having a problem with this plug in. If I add any new videos to my video page, the videos disappear and are replaced with the code.

I have 75 videos listed on my video page currently. Is there a limit on how many I can have listed?

I removed the videos that made the code show up (I tried 3 different videos and got the same result from all 3), so if you view my videos page it looks fine. If you want to look, here’s a link to my videos page: https://behindthethrills.com/videos/
