Feature image is NOT showing in Newspaper7 theme

I recently purchased Newspaper7 theme.

Featured image is NOT displayed while viewing the post after installing Newspaper7 theme.

By the way, featured image area is seen as blank space and when we click on the featured image area or blank space, it opens the featured image or loads the image in the browser window or tab :

However, if I switch to my earlier theme or some other theme featured image is showing up or displayed as expected.

Only with newspaper7 theme, featured image is NOT displayed.

Also I tried revolutionary slider and a post with grids or grid with slide, etc – It is NOT showing the featured images.

Featured images are NOT showing in the grid with Newspaper7 theme :

Note: I have tried clearing all cache (W3 Total Cache plugin) and purging everything from my cloudflare CDN but I still see the same issue.

Appreciate your quick help.

You have a strange line of CSS causing it

body.td-animation-stack-type0 .td-animation-stack .entry-thumb, body.td-animation-stack-type0 .post
img {opacity: 0;}

You can fix this by adding custom css of this

body.td-animation-stack-type0 .td-animation-stack .entry-thumb, body.td-animation-stack-type0 .post
img {opacity: 1 !important;}

If you go into the theme settings try disabling the lazy loading function as well that might be what’s adding it… Use a plugin like this to get a real lazy load.

Thank you for the sooper sonic response.

Both the suggested solutions works – Adding custom CSS code or disabling lazy loading in theme settings & installing rocket lazy load.

Thanks for your quick help in resolving this issue.
