Hello. Constant Contact sign up form returns the following on submission " Sorry, we could not complete your sign-up. Please contact us to resolve this. ". Looking at the console I see the following: "visitor2.constantcontact.com/api/v1/signup_forms/4bebefad-1dd8-452c-9b90-641051eedc19:1 Failed to load resource: the server responded with a status of 500 (Internal Server Error)" Any help would be very much appreciated.
