I've been using this plug in and haven't had problems before. Recently made a new site, and am having a little trouble.
So far, I have three videos posted, I have the "automatically set thumbnail to featured image" disabled. I also have smartyoutube plugin with no thumbnail option set.
Only one of the three videos keeps having a problem with a featured image appearing, even after manually removing it. The post that has the problem was scheduled to be posted in the future.
Hopefully someone is able to help me out with this.
