There can be quite a few reasons that your store is not yet connected to your Facebook fan page.
Please check which alert best describes your case:
- "This application is already installed for all applicable pages"
You need to browse to your Facebook fan page and click on the new "Shop Now" tab.
If this doesn’t help, please follow Re-connecting your store to your Facebook fan page guide.
- "Coming soon" screen
You need to log in to your Facebook fan page with the same Facebook personal profile you used to sign up to StoreYa. If this doesn’t do the trick, you need to follow Connecting store to Facebook guide.
- "You do not admin any pages for which this application can be installed"
You need to create a Facebook fan page. See How to open a Fan page to do so.
