First of all, you should absolutely update Joomla, you're 21 versions behind (current version is 2.5.27). It might not solve your problem, but it will absolutely make your Joomla safer. From your screenshot I can also tell you're using VirtueMart 2.0.10, the latest version is 2.6.10. Please update both. Just make sure to take a backup first, I recommend Akeeba Backup (free or pro version).
As for your products not showing up: Please make sure you have created a menu item to display them, and set it up correctly. I can't see anything wrong with your configurations on your screenshot. Can you try this URL (replace
YOURSITE.COM with your real domain name):
You should see your categories, a couple of recent products and others, depending on your settings.
Normally, you should create a menu item for VirtueMart in order to display products:
Make sure filtering options are correctly set if your products still don't show up.
In addition, several modules are available that can display items from one or more categories, or based on date, or hits etc... (There are about 550 extensions available for VirtueMart in the Joomla Extensions Directory).
