Hello,

Make sure that you are using the latest version of theme and Woodmart core plugin.

Please try reconfiguring instagram API as mentioned in our detailed documentation:
https://xtemos.com/docs/woodmart/faq-guides/setup-instagram-api/

And make sure that you use the API option from the element as well. Because our AJAX Method is now blocked by instagram. Only API works.

Regards.
