zarahjane1 on "[Plugin: MailChimp for WP] Enter valid email address error"

Hi there, I've just configured MC4WP on a customers website http://www.envirolights.co.uk, but whenever I try to submit an email address it won't accept it saying 'Please provide a valid email address.'

I have used the shortcode both in the News Sidebar widget area and on the Homepage, and both areas show same message.

I am running the Kallyas Theme, with Plugins: WooCommerce and Recent Posts Slider.

I would really appreciate any help with this!

Thank you :-)
