I did not upload Featured images and I cannot do it.
I uploaded a lot of posts from a csv file and I need the preview of the video to appear in the post grid (even if it is not the post grid, I need the preview to appear automatically)
The result should be the same as this page https://www.prodotti-dietahlife.it/cat/video/
The page I need help for is here (not published): https://prodotti-dieta-erbalife.it/video-prova-anteprime/
ANOTHER PROBLEM
Homepage cannot be normally scrolled with the mouse wheel. How is this possibile?
