Background of the issue:
I am trying to use my site in English, but when I add a product to the cart, the site switches to my default language, German. The bar saying 'go to cart' remains in English. Here is the link to a page where the issue can be seen: hidden link
Symptoms:
When a product is added to the cart, the site changes from English to German, but the 'go to cart' bar stays in English.
Questions:
How can I prevent the site from switching languages when adding a product to the cart?
Why does the 'go to cart' bar remain in English when the site switches to German?
The language parameter seems missing when you try to add a product to the cart.
Have you tried temporarily switching the language format to "Different languages in directories" in WPML → Languages → Language URL format? Check to see if the issue still exists after making this change.
