[تم الحل] shipping method problem on translated webpage

Background of the issue:
Hello, checkout is not working on the translated page, it says "No shipping method has been selected. Please double check your address, or contact us if you need any help"

How can I resolve this problem?
I tried making shipping classes not traslatable and it solved the problem, i was able to proceed to checkout. But then I got the warning error in admin:

"Some taxonomies in your site are forced to be untranslatable. This is causing a problem when you're trying to run a multilingual WooCommerce site.

A plugin or the theme are probably doing this.

What you can do:

1. Temporarily disable plugins and see if this message disappears.

2. Temporarily switch the theme and see if this message disappears.

It's best to contact WPML support, tell that you're getting this message and offer to send a Duplicator copy of the site. We will work with the theme/plugin author and fix the problem for good. In the meanwhile, we'll give you a temporary solution, so you're not stuck."
