Search parameter does not work

I’ve not made any changes for this.

Can you provide an example of where it doesn’t work?

According to what I have recently read, listtype=search was deprecated on 15th November. It has been replaced by search.list.
In my own instance, all the pages that were using search have stopped working (this is not using your plugin but php code). I was looking at installing yours but when I test it the search property doesn’t appear to be working. Maybe this is the same issue?

You’re right! It appears they announced this in October, with one month’s notice – https://developers.google.com/youtube/player_parameters#Revision_History. That’s not brilliant, and I hadn’t spotted that at all.

The alternative is to move towards using the API, which I currently don’t use, and would be a big code refactor. I intended to do this eventually but it’s not the top of my list right now.
