Hello,
thank you.
I have made a copy of the website at https://shop.a-z-webdesign.de/ (the access data are the same). There I deactivated the child theme, deactivated all plugins that do not belong to the theme and adjusted the settings under Status. Unfortunately, the result is the same as before.
Bets regards,
Chris
