TCPDF ERROR: Some data has already been output, can't send PDF file
i am trying to export to pdf, why this error appears?
And also i tried to export to excel,where i am getting special characters and bad alignment.
Can i get the reasons and resolving solutions?

Hello,
This Error occurs when you have something echo'd before $g->render() function call.
It may be white space OR php warning. Please recheck by viewing source of error page.
You might need version update for excel fix. I'll be emailing you v1.5
Thanks.

Thnks, i got the error and working fine,but still i'm wondering to know and let others do know.
i have,
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Oops some thing went wrong in connection");
mysql_select_db($mysql_database, $bd) or die("Oops some thing went wrong in database");
as it is in any other configuration page,why is it not rendering anlong with this 'die' statements

May be, this is because the lib internally uses ob_start() and ob_get_clean() functions, which prevent from echo on some cases.
