I got it. Thank you so much quepitas.
Hi,
I have a trouble with video thumbnails also. My themes is Hueman.
I go to video thumbnails setting, debugging and test thumbnails and it works very well, but in my post, it shows that “We didn’t find a video thumbnail for this post. (be sure you have saved changes first)”
I add “video” in custom field (option) also but it doesnot work.
Please help me to solve this problem.
Thanks so much.
