Problem with Bulletproof Security - Error 500


I've got Bullet Proof Security installed on my networked site, (Pro Sites), and when I tried to activate it in one of the networked sites, (when I tried to secure the Admin folder), it caused the site to throw a 500 error on all the sites, (including the main one & all dashboards).

By deleting all the HTACCESS files on the server I've got it so that the main site is OK but all the networked sites are still showing a 500 error - HELP !!! :slight_smile:
