site not displaying properly

[NAS]

Hey I've noticed my site http://www.notasausage.co.uk/
isn't displaying as it should. None of the carosels are showing.

and the front page has gone. I've updated all plugins and wordpress, along with laytheme.

i am getting this message in my dashboard refering to site health.

Your site could not complete a loopback request Performance

Loopback requests are used to run scheduled events, and are also used by the built-in editors for themes and plugins to verify code stability.

The loopback request to your site failed, this means features relying on them are not currently working as expected.
Error: cURL error 28: Operation timed out after 10001 milliseconds with 0 bytes received (http_request_failed)

Dear @NAS

In your admin bar > Tools > site health - what PHP version is running?

Also before proceeding just to be sure that these steps dont apply to you:

• Wordpress, Lay Theme & Laytheme's Addons are all up to date ?
• Any Custom CSS or JS that may interfere is temporarily removed.
• Any third-party plugins de-activated to see if this resolves the issue.
• If using a WordPress Cache plugin, disable it or clear your cache.
• License key not activated - (in website blank situations or button not available)
  If your WordPress Dashboard shows a warning "PHP Update required"
  please update your PHP version in your webhost control panel.

This is the console readout:
