Hi. I installed your Newsletter plugin on four WordPress sites hosted on Dreamhost. I configured them for double optin with a welcome email. It seemed to be working fine at first when I tested it, but people were getting error messages after clicking the email confirmation link. They were added to the mailing list but remained unconfirmed.
So I’ve been testing with some of my own email addresses, and got a rather unexpected result. If I’m logged in to the WP site as admin the subscription works perfectly, and unsubscribing works fine too.
But if I’m logged out when I try to subscribe I get this error message after clicking on the email confirmation link, or when I try to unsubscribe if already subscribed.
ERROR: Sorry, there was an error. Please be sure JavaScript and Cookies are enabled in your browser and try again.
Have you any idea why that happens and how I can fix it?
