Hello

I’m setting up the first video gallery using your plugin. Instead of the thumbnail image (png), it shows a white blank image.
This is how its showing: https://postimg.cc/21fcjPfF

Thumbnails are showing fine inside the plugin. See here: https://postimg.cc/hfMkwDmQ

Can you help me understand what is wrong & how to fix this?

Thanks
