Payment does not worked

Hi, I am trying to pay for a 1 month business account (voting to occur from Sept 26-30) but when I validate my bank card info it says "BraintreeError: The data passed in verifyCard did not pass validation checks.". We tried with our institutional card (VISA) and 2 personnal ones (mastercard) and get the same message each time.
We are based in France, and all card are from French banks, and used regularly for online payments.

Hi Clément,
Are you using any ad block extension in your browser?
Can you maybe try another browser?
Often this is the solution to this problem.
Kind regards
Philipp
