I installed Subscribe2 4.12 with WordPress 2.7
After following the installation instructions, the subscription form appears on the page, and appears to be working. But, when I enter an email and click "Send", I get this message on the following page:
"Sorry, there seems to be an error on the server. Please try again later."
Seems like it must be a basic problem, but I tried searching through the other WP forum posts about Subscribe2 to no avail. If there's any other information I can give you to help you help me, I'd be glad to.
