Then you are buffering your output, which can be good on a production
system (but is not always). You shouldn't be buffering on a development
system, however, - it hides errors such as this (which have a habit of
showing up at the worst possible time).
I suggest you comment out the output_buffering (or set it to off) in
your development system.
