User submit the subscription and it says that "the account is not active"

When a user submit the subscription it says that the account is not active. OMG this is bad :slight_frown:

Why is this happenning? By the way even the pop up form is saying that, I receive an email like a user is being subscribed, but with empty fileds on name and email. And the test user is not being subscribed either!

P.S: 4 people already contact me to complaint about this register form issue. They think I am an scam... very upset!
