Cannot modify headers information

[michi]

Hi everybody.

 

I'm working on my machine and got this message when i finish a sale. How can i resolve it?

 

Warning: Cannot modify header information - headers already sent by (output startes at c:root\......\includes\classes\email.php:502) in c:\root\....\includes\functions\general.php on line 28

 

Thanks all! :)

I find this link that help in part of my problem:

 

http://www.oscommerce.info/kb/osCommerce/G...mon_Problems/15

 

The error that apeear for me came together with other error that is:

 

Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost"port 25, verify your "SMTP" and "semto_port" setting in php.ini or use ini_set() in c:\root\.....\includes\classes\email.php on line 502

 

I'm working locally and i understand that in this case, the other warning came in function of this one.

 

When i do it on a web server it woks succesfully. I think that it won't cause any trouble. ;)
