When a user tries to log into Loftware WebAccess listed as a user role, the following error message is displayed on the login screen:
MSG104: Rules Engine Error
This error may occur when an Administrator logs into Loftware WebAccess and applies a rule that specifies a device name that has already been specified in another rule. When a non-Administrator user tries to log into Loftware WebAccess, they receive the MSG104 error.
To resolve this issue, the Administrator needs to delete one of the rules and/or change the "device name" that is referenced in the IF THEN logic.
