I am trying to implement Paypal's digital goods express checkout on a Codeigniter website.
I am using mod rewrite to take the index.php out of the Codeigniter URLs, and so when Paypal does a call back to my website with ?token=xxxx appended on the end, I get a 404 error.
The flow of events gets stuck when Paypal does this callback to the website. The pop up appears but just stays on "loading...".
Any help would be greatly appreciated.
EDIT: I have just changed the uri_protocol in the config file to be:
$config['uri_protocol'] = "PATH_INFO";
And now I can access $_GET variables, but the window that pops up still wont go any further past "loading...".
