Hi sweetcell,
I only changed the line 104 to:
$find_feedkey = $wpdb->get_row("SELECT umeta_id,user_id FROM " . $wpdb->prefix . "usermeta WHERE meta_value = '" . $wpdb->escape($submitted_feedkey) ."'");
The plugin works also with subscribers as I have an admin user and several subscriber users (and tested it). But I am also using the plugin “User Access Manager”… I deactivated the inheritance of the RSS access rights. This could be “your” solution or maybe coincidence.
Does this make sense?
