Unfortunately, our paymentswiki pages don't work without JavaScript. We've got a link to this page in the non-js message:
https://wikimediafoundation.org/wiki/DonateNonJS
But... that page just redirects back to donatewiki, which has a 'please enable JavaScript' message.
Should we change the paymentswiki message to say something more like 'sorry, use a different browser'? Or is there something useful we could put on that foundationwiki page?
