Store not accepting payments Stripe error

Hello WPMU, I have this issue that my store isn't taking payments through Stripe and it's displaying the following message after attempting to make a purchase :


Your account cannot currently make live charges. If you are the site owner, please activate your account at to remove this limitation. If you are a customer trying to make a purchase, please contact the owner of this site. Your transaction has not been processed.

The keys are right and live. I'm here because everything I've tried so far has failed (reassigning keys, switch back and forth test mode, disabling plugins, etc...)

Need help Thanks.
