Bad news I'm afraid:
I thought this looked like a great ecommerce plugin since it was rated highly. But after installing, which puts it in "test mode", I spent a good bit of time exploring it before trying to change the status to "Live". Huh, where is it?
How can that be missing from something that's put out there for people to download? You'll find you may have wasted a lot of time since this is a known issue, even though supposedly the Use Google's Libraries plugin may fix it (another plugin to fix this plugin??? :( It didn't work for me. Good grief, WordPress should put big red check marks by plugins that have this kind of a problem, even if it's just temporary.
