Reply To: Extra thumbnails loaded and other

Hello,

12. Product page and the image size are the functionality of Woocommerce such customization is not covered by our support. Disabling zoom will not reject uploading full-with images moreover there is no zoom on mobile.
You can hide the bottom for enlargement:

body .product-additional-galleries {
    display: none;
}

16. As soon as WordPress updates, we shall also update. Meanwhile, we run this version to be compatible with other plugins.

18. Remove the dot in the class field https://prnt.sc/odnysp and try again. Or set this font in Secondary font and choose from the drop-down.

20. Contact your host support and ask them to enable this function on your server file_get_contents()

Best Regards
