Background of the issue:
I am trying to translate the checkout page using the short-code [woocommerce_checkout] on my site hidden link. The specific page I am working on is hidden link.
Symptoms:
WPML can't see the translation string for 'Billing details', 'Additional Information', and 'Your order'. No scanning helps.
Questions:
How can I make WPML recognize the translation strings for the checkout page?
Thanks for contacting WPML forums support. I'll be glad to help you today.
1) Please go to WPML-> Theme and Plugins Localization and scan the WooCommerce plugin.
After that, please go to WPML-> String Translation, search for the strings, and translate them.
2) Could you please share your Debug information with me?
You can read a detailed explanation about it here. (http://wpml.org/faq/provide-debug-information-faster-support)
The debug info will give me much information about how your site is configured.
