Recently updaated wordpress, theme, and woocommerce. The cart icon in the header is missing. I tried activating parent theme instead of child theme and the problem is still there: http://prntscr.com/e7663l
2. As for the gallery issue, I’ve enabled the option “Enable slider for gallery images” in Theme Options > Single Product Page. Check images gallery now.
Quantity field and “description” and “review” titles are shown properly: http://prntscr.com/e7b1qm http://prntscr.com/e7b1su
Please check in other browsers and let us know the result.
