Hey Rui,
I got this reply from a dude working for WPML, can you help me out.
Hi,
Thank you very much for your help in debugging this tricky issue.
I’ve been checking into your site and found the following.
When you switch themes, all WooCommerce german strings are perfectly translated. So the language packages are loaded and recognized. Please check that and let me know if I missed something.
I think that your theme uses his own .mo file to translate WooCommerce strings. If you go to WPML > Theme and plugin localization > Select how to localize the theme and check “Translate using .mo files” you’ll see that JUST the German file is missing. See the screenshot attached.
So, I think that you’ll need to get that files or use the string translation feature for the German language (which it’s working fine: see “DE My Account”).
The context where that string (“My account”) is (“theme swiftframework”) reinforces the hypothesis that your theme .mo files and not WooCommerce .mo files controls the translation of WooCommerce pages.
Let me know if this helps.
Kind Regards
THanks!
