 * I was following a guide to try and add a test product, everything was going fine
   until I tried the checkout.
 * I was hit with a HTTP 404 error, and now I keep getting them when I click on 
   pages or posts.
 * This has happened to my homepage too:
 * Fatal error: WPSC_Countries::get_countries(): The script tried to execute a method
   or access a property of an incomplete object. Please ensure that the class definition“
   WPSC_Data_Map” of the object you are trying to operate on was loaded _before_
   unserialize() gets called or provide a __autoload() function to load the class
   definition in /home/content/p3pnexwpnas04_data03/42/2454842/html/wp-content/plugins/
   wp-e-commerce/wpsc-includes/wpsc-countries.class.php on line 462

 * OK, my homepage has gone back to the example page… But I still get 404 error 
   when I try to go on Checkout or try to go on my pages or posts via wp-admin

 * Hi Apla,
 * Was your site a fresh install or upgrade?
 * There have been other reports of this exact issue and it seems like the cause
   can be an old version of a an object that is cached as a WordPress transient.
 * The easiest thing to do is clear all cached WordPress transients and re-test.
   There are several transient cleaners in the WordPress plugin repository, or you
   can clear them manually.
 * Alson, I have made this plugin [Store Check-Up and Fix-Up for WP-eCommerce](https://wordpress.org/plugins/site-check-up-for-wp-ecommerce/)
   available if you want to check if the transients exist and optionally clear them
   out.
