Thanks for your support. I forwarded the information to the theme author.
I have another issue. I can't find where to add translations for some texts that are on the block-based checkout page (coupons section, tax text, t&c consent text). I tried to find:
1) In the Pages section > Checkout page translation
2) WPML > Translation dashboard > Other texts (Strings)
3) WPML > String translation
4) WPML > Admin Texts Translation
I have attached screenshots and marked in red the texts that cannot be translated.
The issue you’re experiencing is related to the WooCommerce block-based cart and checkout pages. Currently, some strings on these block pages are not translatable through WPML.
We recommend replacing the block-based Cart and Checkout with their shortcode equivalents:
Once you use the shortcode-based pages, you’ll be able to find and translate the missing texts from WPML → String Translation.
If any strings still don’t appear, you can also scan theme and Wocommerce via WPML > Theme and plugin localization and then translate them in WPML → String Translationm
But how can I translate the block-based checkout page?
Your support previously wrote:
"Translating strings from JavaScript files is still in development. In the meantime, please open a ticket on the support forum, and we’ll be happy to help you implement a workaround."
So, what is your solution other than switching to a shortcode-based page?
