An error occurred | WordPress.org

I am trying to use my credit card to test on the donation form and it’ saying, “An error occurred, please try again or try an alternate form of payment.”

Then immediately it takes me off the page with the donation form and to the /checkout page. And if I make a donation from that page, it works.

So I’m confused why can’t I make a donation from the form but it has to go to the .checkout page
