This plugin should not be displayed as a tested version, it should be a beta at best.
Installation and Uninstallation:
1) BACKUP YOUR DB & FILES beffore install as it may completely damage wp installation.
2) sessions (/temp) directory bug which is difficult to fix for beginners esp ones who do not have access to php.ini file on their servers. Creating a /tmp directory at root level is not going to help (in contrast osCommerce allows you to change the directory path from within admin panel). Lack of this function makes this an amateurish attempt.
3) uninstallation is even more difficult as only php files are removed leaving behind a trail of WPSC folders and files that cannot be removed (yes, even with FTP software). Database entries are also not removable and needs manual clearing up. BE VERY CAREFUL and make BACKUP before attemting to do this!!!
4) Default directory settings were also amended (for some reasons) as my plugins folder could not be located by WP. Left me nothing but to do a clean install
5) “contact your hosting provider” seems to be the solution at forums supporting this plugin
