Hey, So the plugin works great for me except, the shop will not show unless you are logged into the site. I've got no idea why that would be the case. I've tried using the minimum shortcode and the extended as well on several pages and achieved the same results. I've also deactivated all unnecessary plugins.
From looking at the code, it appears that it's not even writing to the page.
Here's the site: http://www.mk837.com/merchswag/
Any help would be appreciated.
