Hello Nick,
Well yes, things have changed a great deal as far as match setup and the Stripe system.
I am making an educated guess here. Of the 2 clubs you manage and the 3 clubs you help manage only one of them has any online payment set up with a match currently taking a large registration payment. We are talking about The Hub City Hosefest in Hattiesburg are we not?
The problem you are experiencing is based on not updating the stripe account to Stripe Connect. This box is in that clubs main page.
I believe this is why your payment are not working. Without the update the system after Sept 1st will not work.
My suggestion is to take a look at these tutorials, they should help you navigate the new system.
