Paypal Express Checkout Error

[themilkman]

I have installed the Paypal Express checkout got the API username/password & signature and set to live server. Whenever I try to make a purchase using paypal I get:

 

Security header is not valid

 

and then cannot make the payement.

 

Please can someone suggest how to fix this?

 

BTW I have an SSL certificate installed but I have not changed any oscommerce file yet for the SSL.

 

Thanks

Okay, I have spoken to my hosting company and they say that my SSL cert is installed for www.capitaldrinks.com

 

I have spoken to Paypal and they have looked at the error as well and they also say that it is an issue with osCommerce.

 

Paypal is set up with api username/password/signature and server is set to live.

 

The error that I get is:

 

Security header is not valid

 

When trying to make a payement using paypal express checkout.

 

I have changed the configure.php file as follows:

 

<?php

define('HTTP_SERVER', 'http://www.capitaldrinks.com');

define('HTTPS_SERVER', 'https://www.capitaldrinks.com');

define('ENABLE_SSL', true);

define('HTTP_COOKIE_DOMAIN', 'capitaldrinks.com');

//Bal 27/02/08 added www.

define('HTTPS_COOKIE_DOMAIN', 'www.capitaldrinks.com');

define('HTTP_COOKIE_PATH', '/catalog/');

define('HTTPS_COOKIE_PATH', '/catalog/');

define('DIR_WS_HTTP_CATALOG', '/catalog/');

define('DIR_WS_HTTPS_CATALOG', '/catalog/');

define('DIR_WS_IMAGES', 'images/');

define('DIR_WS_ICONS', DIR_WS_IMAGES . 'icons/');

define('DIR_WS_INCLUDES', 'includes/');

define('DIR_WS_BOXES', DIR_WS_INCLUDES . 'boxes/');

define('DIR_WS_FUNCTIONS', DIR_WS_INCLUDES . 'functions/');

define('DIR_WS_CLASSES', DIR_WS_INCLUDES . 'classes/');

define('DIR_WS_MODULES', DIR_WS_INCLUDES . 'modules/');

define('DIR_WS_LANGUAGES', DIR_WS_INCLUDES . 'languages/');

 

I still get the same error.

 

In the url I get:

 

https://www.capitaldrinks.com/catalog/shopp...s%20not%20valid

 

Any suggestions here would be great.

 

Thanks

Also just to add, I am on a shared server.

Okay its working now.

 

 

What I did was delete my signature from my paypal profile and then request a new set and then added them in admin.

 

Now everything works. ;):thumbsup:
