This was posted on the support forum over on wponlinestore.com, thought here might generate more ideas or input.
I'm running a fresh install of WP 3.5.1 along with a fresh install of WP-online-store 1.3.1. Everything unpacks and seems to work perfect, except when you click on any demo products OR store links (like categories, shopping cart or my account) you end up at a blank page.
It really seems like something with the link structure or permalink structure, but I've tried every configuration without success. I do plan on purchasing the SEO Friendly URL's add-in - but want to make sure the plugin works fully before modding it.
Any thoughts? Something I need to tweak or change in either platform somewhere?
