Hi Agustin
Check through your code prior to the session_start(); command. You will
have already output some text to the browser, and since headers (and
cookies which are contained within headers) need to be sent before any
output, this error is happening.
Look for any print, printf, or echo commands. Also look for
whitespaces, tabs etc. before the session_start();
Bear in mind your include('file') statements, they might be causing the
problem, rather than the code in the file you're working on.
HTH
