Hello, Nataliyag2,
Thank you for using our theme.
Please post different questions via separate topics, then you will get answers fastest because sometimes different persons work on different requests.
1/ Go to Elementor > Settings > Integrations > WooCommerce > Choose Disable to opt out of using Elementor’s Mini Cart template https://elementor.com/help/menu-cart-widget-pro/
Clear all cache and check the result.
2/ WooCommerce > Settings > Shipping options > Enable the shipping calculator on the cart page
3/ Try to add the next code in Theme options > Theme custom CSS > Global:
.etheme-product-grid-title a, .content-product .product-title a {
color: #222 !important;
}
4, 5/ There are no such options, unfortunately.
6/ Please read this article – https://woocommerce.com/document/related-products-up-sells-and-cross-sells/ Related Products and Up-Sells are different things. Related products cannot be specified in the admin, but can be influenced by grouping similar products in the same category or by using the same tags.
7/ Could you provide temporary wp-admin access?
To provide wp-admin access, you can create a new user account with administrator role via the Dashboard, and provide us with the username and password via the Private Content area.
Kind Regards,
8theme team
