After making a payment through PayPal I am brought back to my download page. When I click on the download link for the pdf file I get this error.

403 Forbidden
You don't have permission to access /pub/.wwphhmgitwksbjcfo/xxx.pdf on this server.

I contacted my host because I read in this forum that A 403 error means that rules in the webserver software prohibited you from doing what you were attempting. My host replied they couldn't help me because it was a configuration error.

My site is a fresh install, no addons I am running version v1.3.9h

In Attribute Setting I have
Enable Downloads = True
