Just black box being showed

What is your playlist ID?

I see my video but all I see is a blackbox on the right side with no videos. I can open playlist from the top of the video, am i doing something wrong? Thanks so much.

If you replace your playlist ID with this one, are you able to see the thumbs?

When I did what you said above I did see the thumbnails. I don’t when I put in my playlist ID. [ypt playlist_id=PLinrKbciW3UzLDuhf9P36POP4kqlCcmYY]

There is a “Private Video” in that playlist. Please remove it from the list or make the video public and post here with the results.

Upgrading to version 0.5.1 should also fix the issue.
