I recently changed the theme on my website, and now all my videos, which were used on the posts with this format:
[youtube id="only the id here" width="600" height="350"]
are not understood, and inside the posts like this one.
The following message is shown where the video is supposed to be:
Please enter the url to a YouTube video.
How can I make it so I don't need to go into all the posts I have that has any video inside and edit in a way that WordPress will embed it?
