 * You may have a conflict with another plugin. It would help if you posted the 
   whole error message.

 * The issue is with PHP 5.4.x – I get the same error (reprinted below) when I try
   to install eShop on a host running PHP 5.4. I do not get the error when I install
   the same version (latest release) on hosts running PHP 5.3.x.
 * PHP 5.4 will no longer allow us to define function variables using super-global
   names; e.g. I can _pass_ `$_POST` to a function, but I cannot, in that function’s
   definition, name my parameter `$_POST`.
 * Here’s the error message I got from WordPress:
 *     ```
       Plugin could not be activated because it triggered a fatal error.
   
       Fatal error: Cannot re-assign auto-global variable _POST in
       /wp-content/plugins/eshop/cart-functions.php
       on line 767
       ```
   
 * I tried just changing that particular function definition to see if it would 
   install, and the error popped up again from other locations in the source.
