I used Softalicious on cPanel to install Magento 2.2.5 a few days ago. My web host (Afrihost in South Africa) has me on PHP 7.1 (and it seems that 2.2.5 will not run on less).
After seeing that my Cron jobs seemed not to be running (no stock items being displayed on the site), I set up to receive emails with output from Cron jobs, and get the following message:
"Default PHP version ea-php56 does not have a CGI binary installed, exiting".
Looks like something is missing at server level !
As for Magento 2.2.5 Minimal PHP version is required to 7.0.13.
So if you have PHP version 7.1 then i think that won't make any issue !
Refer this release notes for magento 2.2.5 - https://devdocs.magento.com/guides/v2.2/release-notes/ReleaseNotes2.2.5CE.html
Hope it helps !
