Gallery thumbnails not displaying

Hi,

Great theme.

The thumbnails on the bottom of the gallery are not displaying.

Can you tell me how to make them display?

It’s a similar issue to the issue in this thread, which was never resolved: https://hb-themes.com/forum/all/topic/thumbnail-navigation-problem-for-gallery/

P.S. I have a featured image set. I saw you mention that as a solution in a different thread. Thanks.

Warmly,
Sam
