Hi @wpress2010
After investigating this issue, I realized that this is happening on the page you shared with us simply because the FooGallery CSS file is not being loaded.
The CSS stylesheet is not being loaded because your site is being loaded using HTTP while the CSS file is being loaded using HTTPS thus causing a mixed content error, which is blocking the file from being loaded. To confirm this, kindly open the developer console on your browser after loading that page and you’ll see the error message “Failed to load resource: net::ERR_CERT_AUTHORITY_INVALID”
A mixed content warning appears in a user’s browser when the WordPress site they’re trying to visit is loading HTTPS and HTTP scripts or content, such as the CSS script like in your case, at the same time. This can cause problems since HTTP and HTTPS are completely separate protocols.
To resolve this, the first way, for FooGallery, 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 to fix mixed content errors on your site and see if it does help: https://www.wpbeginner.com/plugins/how-to-fix-the-mixed-content-error-in-wordpress-step-by-step/
