Subscribers Automatic and Premanent Re-Direct | Peter's Login Redirect | Forum

Hey all. I inherited a site that uses both WP E-Commerce and Peter's Login Redirect. When I visit the Login Redirect settings page, under the 'Specific Roles' heading, the plugin is setting itself to automatically re-direct subscribers to the products page and will not allow me to change the url to the home page of the site. Whenever I change the redirect url for 'subscribers' and hit update, it goes right back to the products page url. Does anyone know why this might be? Thanks alot!
