If you are on nodebb 1.12.2 you should use the version of db search in your package.json. 4.0.6 is for nodebb 1.13.0 which isn't released yet.
Unable to Embed YouTube Using Plugin
Installed NodeBB Youtube Embed Plugin (nodebb-plugin-youtube-embed) and activated it.
But still, the YT video is not embedded. Just showing the plain URL (link).
Is it a compatibility issue ..I'm on NodeBB 1.14.0-12.
Or do I need to go with any other plugin?
Any fix for it?
Try using this one instead (it works for me on latest NodeBB)
