Hello Rose Tyler
1.- I already tried that, disable all the plugins and try one by one, first enable the Elementor and the XStore Core and try it and the same error occurred, as far as I can see it may be the child theme. https://prntscr.com/shyoz3, now it only sends me to the ticket screen and sometimes to screen 404 https://prntscr.com/shyq2j , https://prntscr.com/shyrhc
2.- Observe another error in the product section despite enabling the display options Add to cart in the front end the button is not shown despite having products with 5 units in stock
