It’s been like this for a couple of hours as far as I know, please fix I really want the current deal!
Try a different browser, I just tried and connected to PayPal fine, it’s a problem on your end not Chrono’s.
Dang it! Ok, thanks man, it was uBlock’s fault; even though I whitelisted paypal, it was still enabled for the buy page. 
Edit: on second thought, that’s really weird because it worked fine the last time I bought something from Chrono, meh. oh well. . .
