[frs-194] After upgrading a FusionReactor 2.0.4 to FusionReactor 3.0.x, I can no longer log in


After using the FusionReactor 3.0.0 installer to update a FusionReactor 2.0.x instance, you can no longer log in. If you were previously logged in, you may receive the following exception when attempting to access the FusionReactor Administrator:

This problem occurs when you have used a blank password for your FusionReactor 2.0.x user (n.b. this was the default for manual installs of 2.0.4). When the FusionReactor 2.0.x instances are upgraded to 3.0.0, the Configuration Upgrader uses the same password for the new user roles Administrator, Manager and Observer. In 3.0.0, a blank password set for these roles disables them, effectively disabling all log-in to the FusionReactor Administrator.


  • Open your reactor.conf file and locate the line which begins user.0=Administrator,...
    • This file is located in /FusionReactor/instance/INSTANCE_NAME/conf/reactor.conf
  • Change this line to:
    • user.0=Administrator,Administrator,21232F297A57A5A743894A0E4A801FC3
  • Restart your J2EE (ColdFusion) server

This will enable the Administrator user with the password admin. The password should then be changed in the FusionReactor Administrator (FusionReactor -> Change Password).
