In the attached image you can see that there’s a white arrow pointing to the next product photo. It’s supposed to jump to the next image when you click on the arrow, but its not happening and I’d like to understand why. How can I fix this?
You should deactivate all plugins except Woocommerce.
Then test if the issue remains. It the issue is gone you have to reactivate the plugins one by one and re-test the issue.
Just realized now that your Woocommerce plugin is not updated to the last major update.
You should update it, but first it’s better to backup everything just in case.
