My PHP/mysql script does not alter any HTTP headers, that is correct.
So if CI is really attempting to send headers after the controller code is executed (which seems wrong to me), how should I proceed? Remember that I'm seeing this error whether I echo the UTF8 data from a controller function or from within a view.
By "set your environment to production," what do you mean? Are you referring to configuration groups in database.php?
