Talked with Stripe about people trying to signup for memberships and then not working... here is the the response from Stripe Directly..
Jumping into help out with your integration questions! That log is for a request that created a token, but not a charge.
Charging a customer with Stripe is a two-step process.
Step 1: You collect a customer's credit card information with a Checkout or Stripe.js form, which is then sent to Stripe. In return we send back a token that you can use to charge this card.
Step 2: You take this token and tell Stripe to make a charge with it, or save it to a customer to be charged later. You will need to setup a script on your server to handle this. https://stripe.com/docs/tutorials/charges
It looks like your application has successful used tokens in the past. It's likely there was some sort of error within your application when this customer entered their information and the token was never used. I would take a look at your server logs to see if you can see any errors.
Hope that helps, let me know if I can answer any other questions for you!
