Hi @hammaddilawar1!
I am assuming that you have moved your products from a different site to the site https://www.juicewrldmerchshop.com/shop/. Please correct me if you’re referring to a different site.
In addition to what @seank123 said, please note that WooCommerce’s built-in Import/Export functionality should work with built-in product types.
I checked your site and noticed that the single product and variable product types are working (mentioned below) correctly.
1. https://www.juicewrldmerchshop.com/juice-wrld-999-shirt-t-shirt/
2. https://www.juicewrldmerchshop.com/juice-wrld-999-snapback-cap-black/
3. https://www.juicewrldmerchshop.com/juice-wrld-999-black-t-shirt/
I see issues with some of the product images though, the CDN images are returning an error (like in the below listings).
1. https://www.juicewrldmerchshop.com/juice-wrld-smile-999-t-shir/
2. https://www.juicewrldmerchshop.com/vlone-juice-wrld-999-print-t-shirt/
Reference: https://d.pr/i/qe42Jv
The issue with these images seems to be with the CDN; I noticed the image paths are from alicdn.com; like https://ae01.alicdn.com/kf/H38b5e411e07043e5a4f42d646b6b316ey.jpg
If this is the issue you are referring to; then fixing the image paths should solve the problem. BTW, I was able to add these products to the cart, so I don’t see any WooCommerce-specific issues. But, feel free to correct me if I missed anything.
In case you are referring to a different problem or have questions, please pass us more details, like the product type, listing URL, and what exactly isn’t working.
Best!
