# WP_PLUGIN_DIR not defined

 * My install was not working because of WP_PLUGIN_DIR being defined in the wp-cache-
   config.php:
 * if ( ! defined(‘WPCACHEHOME’) )
    define( ‘WPCACHEHOME’, WP_PLUGIN_DIR . ‘/wp-
   super-cache/’ );
 * I had to man change to this
    if ( ! defined(‘WPCACHEHOME’) ) define( ‘WPCACHEHOME’,
   WP_CONTENT_DIR . ‘/plugins/wp-super-cache/’ );
 * I thought this was defined in the WordPress defaults?

 * realize that. I guess something is overriding it WP_PLUGIN_DIR was pointing to
   WP_CONTENT_DIR …
