Just set up Themeco’s Email Forms plugin v 2.0.3 and integrated with Mailchimp.
The sign up hangs, turns out there is the following error in Chrome Console:
Uncaught TypeError: $(...).alert is not a function
at make_alert (main.js:39)
at Object.success (main.js:160)

Links through to this line of code
function make_alert( content, class_name ) {
return $('<div class="tco-subscribe-form-alert-wrap">' +
'<div class="tco-alert ' + ( class_name || 'tco-alert-danger' ) + ' fade in man">' +
'<button type="button" class="close" data-dismiss="alert">×</button>' +
content +
'</div>' +
'</div>').alert();
}
