Error on subscription and redirection on loop on confirmation link.

Hello,

unfortunately I have two issues with this plugin:

First: the subscription.php dies with

Wrong email

even though the email is set. But the data is stored, the confirmation request mail is sent, but then the next issue…

Second: After clicking the confirmation link the user is redirected infinitely to the same location. Here the headers via curl:
