As detailed to our affected community web-hosting customers previously, today we have retired PHP 5.6 from our community web-hosts (www10, www11, www15) and replaced them with PHP 7.2 (which is supported until 30th November 2020)
This is due to the retirement of security support for PHP 5.6 by the vendor on 31st December 2018.
We take the security of our shared platforms very seriously, and will not run outdated software on these.
