Accordion Not working

Hi,

I can see some Javascript error on your page and some mixed content errors.

Failed to load resource: the server responded with a status of 500 (Domain Not Found)
respond.min.js:1 Failed to load resource: the server responded with a status of 500 (Domain Not Found)

Another big problem you must fix is that the theme is including the jQuery file manually from the theme folder instead of enqueue the script:
https://yu……com/wp-content/themes/yummymandarino/js/jquery.min.js

jQuery is included in the core WordPress and must be used following this article:
https://developer.www.ads-software.com/reference/functions/wp_enqueue_script/ . You will run into many issues because of this.

Once you properly enqueue the jQuery, it will probably be OK.

Thanks
