Apologies for the slow turnaround here, @ejpt99
Please check the payment error logs at Donations > Settings > Payment Gateways and see if there is any more information there as to why donations are failing. click on the eye icon beside a few of the log items for the full error message from Stripe.
Usually when payments are not getting to Stripe, it either means that the site has been disconnected somehow or that something is not configured correctly.
Another thing to try is switching to the “Stripe Checkout” gateway to see if donations go through that way.
One other step is to navigate to Donations > Settings > Advanced and change the Script loading location.
Also, a few more questions:
1. Are the donors attempting and failing to make donations ones who have given before?
2. Are these one-time or recurring donations? (if you are using our Recurring Donations add-on and have an active license please submit a priority support ticket at https://givewp.com/support)
3. Have donations ever gone through, or not?
Either way, we definitely want to get this resolved with you. Keep me posted.
