Pages with 2 side panels not responsive

Hi jmkt. Are you using a different page template for that page? Almost all the links in the header are commented out on that page:

<!-- <link rel='stylesheet' id='contact-form-7-css'  href='https://www.housecleaning-edinburgh.co.uk/wp-content/plugins/contact-form-7/includes/css/styles.css?ver=4.3' type='text/css' media='all' /> -->

Many thanks for your reply.

I played around with the templates and noticed it was fine sometimes but the problem came back when I cleared the cache.

When I deactivated WP Fastest Cache the problem was solved. I usually like and use WP Fastest Cache but seems to be the problem here.

Thanks again.
