Fail to accept donation due to third party javascript, XHR, and iframes required by Stripe

[kenrestivo]

Error: This customer has no attached payment source or default payment method.

Wat?

Turns out quite a few Javascript, XHR, and iFrames were required, and my umatrix security settings blocked them all.

Might be good to mention to those of us who have zero trust of anything on the web to turn off our paranoid umatrix options.
