Well actually, the develop of the woocommerce social share plugin sent me an update to his plugin and found a link to page on fb’s dev site that allows you to enter a specific URL to manually refresh the cache.
So everything is working now, but I’m not sure what role your Open Graph plugin is currently playing in it.
The theme is having issues of displaying a product image other than the feature image as the main product image, which is a known bug in the theme its devs say will be corrected in a pending update, so we’ll see what happens then.
But from what you see in the code, everything is working correctly, right?
I actually see it in there twice. Perhaps that is once from your plugin and once from the social share plugin.
Thoughts?
