Autoscroll using Shortcode

I used the console shortcode on a classic Omeka site and the auto-scroll works perfectly. I used the same syntax on another classic Omeka site but the auto-scroll does not work. The browser’s javascript console said that the page was loaded over HTTPS but requested an insecure element at HTTP://…This request was automatically upgraded to HTTPS, For more information see Chromium Blog: No More Mixed Messages About HTTPS

carousel-updates:196 Uncaught TypeError: jQuery(…).jcarousel is not a function
at carousel-updates:196:39

Uncaught TypeError: Cannot read properties of null (reading ‘click’)
at carousel-updates:259:39

The site that triggered the error uses the Philly theme.
How do I correct this? Thank you in advance for your help.
