[PHP-WIN] DaDaBIK 2.1b beta released
The header() command is very sensitive. No data (including a stray space)
can be sent to the browser before a header() command is called. If you take
out the include(conex.php); line (or just take out the data that it echoes
to the browser) you'll be in fine shape.
