This is how it looks. Clicking on the picture will take you to Youtube.

To fix this you need to do a Rebuild HTML in the post, after that everything works fine.

Tell me how to make a mass Rebuild HTML so that embedded Youtube videos can be played again in the forum without switching to Youtube.

Thank you!

A little warning about that. If you target only posts containing Youtube videos, and don’t set a timer between each rebake, it will make a lot of Youtube requests and your server’s IP might be temporarily blacklisted, leading to broken Youtube embeds.

It happened to me. See:

"Onebox Assistant", crawl for those previews reliably!

Not related, but I used the plugin when rebaking all my posts after a huge import (1,6 M posts), including posts containing Youtube videos. Youtube ended by blacklisting my IP after too much embedding. Installing and enabling Onebox Assistant resolved this issue, and I didn’t need it after the rebake. I disabled it but didn’t remove it (just in case, you know). It was perfect for this task.
