JW Player for WordPress is a great little solution to locally house and present your videos. However, I recently had an issue where my playlist for JW Player would not display. I could see that it was loading and pulling in the list of videos, but even with my Advanced Settings being correct it still wouldn’t show.

With some help from LongTail Video Support (thank you!) I found a solution.
It turns out that sometimes the config attributes for the playlist are not carried over. So, you can force them in your [jwplayer] shortcode attributes.
Here’s some sample code to show you what I’m talking about.
Original:
[jwplayer playlistid="123"]
Updated:
[jwplayer playlistid="123" playlist.position="bottom" playlist.size="250"]
The key attributes being “playlist.position” and “playlist.size” I hope this helps!
