Warning: Cannot modify header information - headers already sent by ...

[ballhogjoni]

I have been on the paypal developer forum and no one replies and helps me out. So I hope I can get some help here.

 

I get this message when I submit the form:

 

Warning: Cannot modify header information - headers already sent by (output started at /home/realfina/public_html/ec/eBayoffers/samples/php/ppsdk_include_path.inc:7) in /home/realfina/public_html/ec/eBayoffers/samples/php/WebPaymentPro.php on line 135

 

and this is my code:

I know what the issue is but I don't know how to fix it because this is a script that paypal developed. Honestly I don't know if I move anything around whether it will screw up the whole script.

On that script at line 7 is where the violating line is. Either an error is occuring there or something I would look into that.
