After someone purchases from Paypal, it goes to a missing page
What’s happening? Well, each time someone makes a PayPal purchase from my site, they are taken to a 404 Page Not Found page.
Why is this? If you’re using the simple paypal integration into a site, at one point in the setup, you have to put in a “Returning page” This is what’s happening. Coordinate with your webmaster to make sure you have the right page.
