We recommend leaving the cache on as you will get better site performance and the edge cache will catch up within a few hours. However, if you don't want to use it or it's causing a problem you can turn it off or flush it by taking the below steps:
1. Go to 'My hosting' (https://my.sgis.co.uk/clientarea.php?action=services) and click 'Manage' next to your domain name.
2. Click on 'Edge Cache' under the 'CDN' heading
3. To turn it off, toggle the 'Global Edge Caching' option or to purge scroll to the bottom and click 'Purge everything'
