The "A fatal error has occurred. Please contact support." error message is associated with the SimpleRisk function that connects the PHP code to the MySQL database. If you are seeing this message, it is a good indicator that SimpleRisk is unable to properly communicate with the database. You should verify that you are using the correct username, password, host, and port in the config.php file. If those all appear to be correct, try manually connecting to the database using the command "mysql -u[username] -p[password] -h[host]".
