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.
First, please update your WPML plugin and add-ons to the latest version, 4.7.1, to benefit from the latest bug fixes and improvements. This may not necessarily resolve your problem; however, we need to work on the newest code available to troubleshoot the issue best.
You can check the latest released versions under "My Account -> Downloads" on this site. Instructions to update can be found here: http://wpml.org/faq/install-wpml/
If you do not see the updates, you might need to click the Check for updates button in the Plugins → Add New Plugin → Commercial tab.
Please remember to backup your database before you proceed.
Changing the language URL format did the trick, thank you! Even switching back to the old format made the page work again as expected. I still can't understand where the error came from but I'm happy to have it resolved!
