Hello,
1) Could you, please, provide us with WP Dashboard access to check?
2) It’s not related to our theme. It’s related to WooCommerce plugin session. Contact WooCommerce plugin about this https://wordpress.org/support/plugin/woocommerce/
3) Single product page displays image that you set in the Theme Options > WooCommerce > Product Images > Main Image Width > set 400px for example. At the same time Thumbnail Width set 300px. Also add the below code to Theme Options > Custom CSS
.content-product .product-content-image img {
width: auto;
}
4) What’s wrong with the mini-cart https://prnt.sc/xnemu2 ? Could you, please, provide us with screenshot for better understanding?
5) Shipping settings are WooCommerce plugin settings. We don’t have options to manage them. So, check the WooCommerce plugin documentation to set it up or contact WooCommerce plugin support https://docs.woocommerce.com/document/setting-up-shipping-zones/
6) Go to Theme Options > WooCommerce > Shop elementor > Sale and Out of stock > enable Percentage discount option.
