Site Behaving Strange!

I have not edited my site (www.socialwiz.co.uk) in a few weeks. However, I noticed that the site is suddenly not loading properly (the homepage). There is a massive white blank at the top when I am trying to open my site on desktop. When I try opening it on mobile devices, I am only getting the red loading balls!

Can you please help?

Hello there,

Please try to disable code optimization/compression from your plugin.
