Great, thanks for opening the ticket guys. I will watch it for updates.

Bump. Anyone has this issue? I just got the 1.1 upgrade on this Theme and still still the issue.

Great recommendation on “Health Check”. Very useful in debugging with clean WP without affecting live site! I will keep all these in mind. Thanks again @nm1com !

Thanks @nm1com for the workaround! Yes Custom HTML Block seems to work for me too. (However I have trouble controlling the embed size when using it though.)

I also discovered that these issues are only happening on the default TwentyTwenty theme. When I switched to a more simpler Theme (eg: Hostmarks), then all the embed Blocks seem to work just fine. Even the Custom HTML Block has no sizing issue. So perhaps this is the default theme issue only?

Hi t-p, thanks for the help. Yes it turns out it was the “Custom Post Type UI” plugin that I have installed caused the issue. I had version 1.8.0 installed, and there is a newer version 1.8.1 pending. I didn’t want to upgrade, but it seems that having simply a pending upgrade can cause these warning message? It seems odd. Anyway, after I upgraded the plugin, then error message is gone.
