Online orders stopped processing payments on 8/29

[Thriv]

We use Woocommerce for our e commerce platform. On 8/29 payments stopped processing, customers received the following error message. Can anyone help us figure out what is going on?

Hey @Thriv,

This error seems to be coming from the site's side. 

You'll need to reach out to WooCommerce to figure out what went wrong here since they're a third party with us.
