warning message

Hi guys,

Sometimes I get the following warning:
Warning: Cannot add header information - headers already sent by (output started at encryptRequest.php:57) in /encryptRequest.php on line 59

What is the cause of such errors?

Thanks in advance!

Any HTML or TEXT passed before you sent the header() command
