FlipFlop 3.0Cart Not Saving
This is a common issue and is almost always caused by something that is specific to your site.
To rule out other plugins and themes, you must first deactivate all other plugins, and use the current default WordPress theme (e.g. Twenty Ten).
If the problem persists using the WordPress default theme with all other plugins deactivated, contact your web hosts and explain that PHP sessions are not being saving correctly.
