I believe there is some sort of server/BPS incompatibility thing going on or maybe some changes in the server’s httpd.conf file would do the trick. You can try manually deleting the BPS root and wp-admin htaccess files to see if the site comes back up. If that works then that tells you that there is a server config/compatibility issue/problem with some or all of the BPS htaccess code in either the root or wp-admin htaccess files. The 500 error could be caused by this really old known issue/problem below. * [https://forum.ait-pro.com/forums/topic/read-me-first-free/#bps-free-general-troubleshooting](https://forum.ait-pro.com/forums/topic/read-me-first-free/#bps-free-general-troubleshooting) * > 500 Internal Server Error After Activating BulletProof Mode for your Root Folder > Some Web Hosts do not allow you to use the “Options” Directive in .htaccess > files.
