Hi @pleighp
I have had a look at this page (https://adisystems.net/new-phone-cases/) and made the same observation. However, on having a look at the developer tools, I realized that the FooGallery CSS script is being loaded as HTTP instead of HTTPS. This causes problems since HTTP and HTTPS are completely separate protocols and leads to a mixed content error and as a result of that, the script is being prevented from working.
The first solution you can try to resolve this is to navigate to FooGallery -> Settings and on the “Advanced” tab, scroll down to “Force HTTPS” and enable it.
However, if the solution above does work, kindly go through this guide on how to fix mixed content errors and try out the various solutions offered and see if one of them does help: https://www.wpbeginner.com/plugins/how-to-fix-the-mixed-content-error-in-wordpress-step-by-step/
Thanks
Kind regards,
Elvis.
