Mail chimp API not working

Hi I Have oceans WP theme, i have created a a mail chimp account,

I Have entered the api info and list ID

Theme panel > Intergrations Tab

For some reason it doesn’t want to work, i do not see any errors. when someone enters there email all it seems to do is refresh the page and nothing is sent through to mail chimp etc.

I have also took the credentials out and it does the same thing.

i am using elimentor editor and when you click the input field it does show edit>> mailchimp,

am i being stupid have i missed something ?

any help would be great thanks
