Although I registered, I can't find the MailMojo list id on the MailMoojo site. Is there a site in English?
This might be the problem...
To find the list ID: Go to the email list of your choice in MailMojo, and look at the last part of the URL. That is the list ID. E.g. given "mailmojo.no/lists/123", 123 is the list ID.
I'm using the coraline theme on dreamhost and I don't see anything on the test site.
On another test site where I'm using the twenty eleven them, the sign up boxes come up but I receive an error message that php curl extension is not installed.
