Websites have a unique identifier used to locate the path to the files on disk.
This unique website identifier, or $website-uuid, is used with advanced configurations for ionCube installation and PHP error logging.
To find the $website-uuid login to your hosting control panel and navigate to Websites > $website
and look at the browser address bar.
Where you find the address bar says https://cp.purely.website/websites/123-123-123-123-123
the $website-uuid
of your website is 123-123-123-123-123
