Hey there.
There was a Domain added to the Installation above.
It is now found at: https://repairyourphone.de
and the Backend is: https://repairyourphone.de/wp-admin
We found there is a problem with the mini-cart view.
When adding an object to the minicart, the price is displayed as 0,00 Euro.
When loading the entire cart, the Price is correct though.
Or when refreshing the page after putting something into the cart, the Mini-Cart is up to date, too.
However, Customers usually don't refresh the page manually, so there is the question, if something can be done here... .
It is a live System BTW... .
There is a Screenshot of the problem attached
PS: We tried to open a new ticket after renewing support but that failed...
