You can call me anytime. I'm often here 9-5pst. That is 4pm-12am GMT.
It looks like you manually created that connection file and the connection isn't referring to the variables set properly.
$conn1_i = mysqli_connect($localhost, $username, $password, $database);
but I think it should be:
$conn1_i = mysqli_connect($hostname_conn1_i, $username_conn1_i, $password_conn1_i, $database_conn1_i);
