Ok, after investigating the problem, I have learned that Woocommerce was using the product thumbnail (120×120) in place of the single product image. So, this may or may not be related to the theme. I increased the size of the product thumbnail and that solution seems ok for me.

I have identified the conflict. It is with the latest update of W3 total cache. Simply clearing all caches does not fix the problem. W3 total cache must be deactivated, and cannot be reactivated, or the icon boxes become invisible. This is a problem, as we need a caching engine and W3 is the the only/ best game in town as far as I know.

I do not see any updates available in the dashboard, updates section, themes section, or theme options. All of the default wordpress themes updated fine, however there is nothing indicating that an update is available for Enfold. My support is current. How do I update to the latest version?
