Danny,
Hey I decided to just embed the form using a text widget from code on MailChimp.
Well I guess I’m the first one to figure it out. I think the main problem had to do with switching domains. I had to update the website URL in the database using myPHPAdmin, and then all other references to the site URL in the admin panel and update my image links and so forth. Everything appears to be back to normal now. I’ll leave this up in case someone else has this problem!
