I installed an upgrade as a pilot version but kept getting server errors (code 500) until the host switched the php from 7.1 to 7.0 and now it seems to be working fine. I'm just wondering if I should be concerned about using Php 7.0 because the upgrade documentation says it's not recommended.
Any idea why PHP 7.1 wouldn't work and PHP 7.0 will?
What's wrong with PHP 7.0?
Thanks!
