Update 1: I just managed to update the core plugin to 4.2.1. Theme is still version: 8.0.8
But I see this to late: Never update the XStore Core plugin if you have not updated the XStore theme to the latest version yet!
Update 2: I’ve updated the theme via the Envato marked plugin to Version 8.2.1. Is it a problem to update the core plugin first and then the theme?
Update 3: I try to simulate the error again. Please wait 😀
Update 4: The mailing problem is solved. I think the older version of the theme doesn’t supported the latest version of woocommerce/wordpress.
I have two new questions: The dropdown menu with a HTML Block doesn’t load. ( https://www.expandsupps.com/media/2022/06/Schermafbeelding-2022-06-21-om-19.37.24.png )And I can’t turn on the new sale booster items.
