I uploaded the youtube-sidebar-widget.php file okay and added it to the widget and added the playlist ID.
It looks like it works, as in the thumbail of the video is there and the title, however, you cannot click it to play the video. There is no arrow image.
Would I have to upload the arrow image as well? If so, how?
What about the js file and the css file that was in the zip file that I installed? Do I have to do something with those?
Thank you for your help! Much appreciated.
