What to do if your you tube video doesn't appear in Drupal?
You have just uploaded a video and it doesn't appear properly as one of the examples below.
1st example
There are chances, the URL you have pasted looks like that:
Drupal doesn't recognize this kind of URL and this is the reason why you get a grey screen.
A youtube URL should always start like this:
https://www.youtube.com/watch?v=
In our example:
https://www.youtube.com/watch?v=X2yZeRiw3_U
2nd Example
There are chances, the URL you have pasted looks like one of these below:
1) https://www.youtube.com/watch?v=Wtq12PCp9OY&list=PL8uB6zI647TsyomGaVohq0pkGlcwO5q7U
Drupal doesn't recognize this kind of URL and this is the reason why you get a back screen
A youtube URL should always have only one ID
In our example:
https://www.youtube.com/watch?v=Wtq12PCp9OY
2) https://www.youtube.com/watch?v=I0aOzfHt4wc&t
&t should be removed from the URL
P.S. We have noticed that unlisted videos do also experience some issues.
