Background of the issue:
I am developing a site with three languages: NL (main), FR, and GB. I am using a shipping plugin, and I want the shipping rates to be consistent across all languages.
Symptoms:
When I place an order and choose a shipping method, the shipping rates are displayed. However, when I change the language, the rates disappear. The shipping rates are added to the translations, causing them not to update for other languages when changed in NL.
Questions:
Do you have a solution for ensuring shipping rates are consistent across all languages?
I made the necessary tests, but unfortunately the results were the same. That confirms that this plugin is not WPML compatible. In this case, you need to reach out to the plugin developer, and ask them for a solution.
They might be able to make the necessary adjustments, so that the shipping prices are consistent across languages. Please reach out and let me know what's their feedback.
