I have just tried installing SuiteCRM v7.11.20 via Softaculous but I get the following message
This script is not compatible with PHP version : 7.4.0+
Do you wish to enable PHP 7.3.28 ? (Might cause issues with your existing installations).
But on the compatibility matrix it indicates that
SuiteCRM 7.11.x is compatible with PHP v7.4 (starting from SuiteCRM 7.11.19)
Thanks in anticipation
