PayPal payment button not appearing

PayPal button was working fine a few days ago but now it won’t appear on the website. And sometimes it shows up in the Sparkle app and other pages it does not. Has anyone else experienced this?

As mentioned over email, you have an incorrect client-id set in Sparkle.

Not sure how this changed, but how do we get a new one to put in Sparkle?

In the payment section of the site settings.
