Hello there,
The gallery images that display in the woocommerce single product page disappear after maybe 5 seconds of the page loading up, we had issues before with some of the new features in woocommerce when we upgraded and therefore disabled those features (zoom, lightbox, slider) in the child theme. The images then displayed as they had previously, as I said, only to disappear after a few moments later.
Do you have any suggestions?
Best,
Team Zendo
