Yendif Player

Hello, I am having a issue with the thumb nail picture for the my category. It was showing up and then it stop, the videos still play. I recently updated my joomla to 3.8.10. not sure if this had something to do with it. here is my website soulrecruitermusic.com/

Strange. I didn't get the issue here. I'm checking the link soulrecruitermusic.com/index.php/404-page

Does it mean the issue solved? If not, kindly get me the exact page link where the issue occurs and the browser name & version you use.
