Good evening Birgit and welcome back!
Thank you for your question.
The “Add to cart” button translation can be found in the following places:
- /wp-content/plugins/event-tickets-plus/lang (event-tickets-plus-de_DE.po andĀ event-tickets-plus-de_DE.mo)
- /wp-content/plugins/woocommerce/i18n/languages AND/OR /wp-content/languages/plugins
In certain contexts, it is possible that the basic WooCommerce language files are used for the “Add to Cart” translation. ThisĀ is why we have to make sure that the files located under point number 2 are properly translated as well.
Let me know if that helps.
Have a great day!
Geoff B.
