Magento - Paypal Express 404 Error

I have added paypal pro (uk) express to my Magento shopping cart. The paypal button now appea开发者_开发百科rs below the checkout button in the shopping cart.

The problem is when I click the paypal button I get a 404 error.

Any ideas?

I reckon you added a payment method for the checkout process or a custom paypal checkout. Activate the debug mode and the error logging in system->configuration->developer. Having a more verbose error message will point you to a more clear error.

404 is page not found error, so wherever the paypal module is pointing the page is missiong. This could happen as a result of malconfiguration or API change or other issues.

Fixed it by following post 5 here: http://www.magentocommerce.com/bug-tracking/issue?issue=8528

I needed to delete the paypal files in the default folder.
