problemer med paypal

bare en tanke:
hvad tror du der sker med din session når du starter en ny session ??

>session_start();
>include_once("config.php");
>include_once("paypal.class.php");

du starter session op igen og resetter dermed den gamle session i config.php, og ennu en gang resetter du din session i paypal.class


jeg vil anbefale dig at pakke alle dine session_start(); ind i en test

if(! isset($_SESSION)){
	session_start();
}

det kan være det, der giver problemer i process.php

I kommentarene på den guide du har fundet står der hvad du skal gøre hvis du løber ind i det der problem.

Desværre, det har jeg også prøvet at kigge på

jeg har prøvet at kigge på denne her og jeg har også prøvet at skrive

 session_start();

ved alle filer i toppen,

Mine filer ser sådan her ud:

config.php

 session_start();
 //start session in all pages
 if (session_status() == PHP_SESSION_NONE) { session_start(); } //PHP >= 5.4.0
 //if(session_id() == '') { session_start(); } //uncomment this line if PHP < 5.4.0 and comment out line above
