Hi there

Exactly the same problem here. As soon as the Plugin was updated to version 5 (via wordpress autoupdate) we’ve received the following error:

Fatal error: Uncaught Error: Call to a member function switch_to_locale() on null in /home/httpd/vhosts/**************.ch/**************/wp-includes/l10n.php:1679 Stack trace:

Thanks for looking into this!

Hi @rainfallnixfig, thanks for your feedback!
I’ve tried that and I can also recreate the same behaviour, even if I try it with a fresh installation of WooCommerce and Storefront.

Here’s a Screenshot of the shipping settings:
https://snipboard.io/vGjmBf.jpg
https://snipboard.io/j0ab7f.jpg
https://snipboard.io/yXo9zU.jpg

And those are the steps to reproduce the issue:

1. Set up a shop running on Woocommerce 5.2.3
2. Set up the shipping options and shipping Zones as seen in the Screenshot above
3. Create a user, that has a billing and a shipping address, but both whithout setting a country/region
4. Login as the newly created customer and add a product to the cart.
5. Go to the cart Page. There you can see that the default shipping zone is selected
6. Update to Woocommerce 5.3.1 or higher
7. Repeat steps 3. – 5.
8. this time, there is no shipping zone set on the cart page.

Many Thanks in advance for your help!
