When I click the Buy Now button, the screen to purchase never loads. I am seeing this with Safari & Firefox. Clearing my cache and cookies does not make a difference. Chrome works

Safari Web inspector gives error: Refused to load https://primatelabs.onfastspring.com/popup-voodoopad/session/nC94e5csT3OwNl2jml9Y3Q because it does not appear in the frame-ancestors directive of the Content Security Policy.

Firefox web inspector gives this information:
