error message about required fields

I read the post from about 6 months ago on this. I am getting this message again in the latest install.

I am not sure if I am missing in the settings an email of where I want the message to send to or post. In the admin settings I do have my email in there.

the error message about required fields says the email has not been entered and the form is not submitted.

Would really appreciate your input

Thank you

Darlene
