Error 500 after upgrading PHP version from 4.4 to 7.2

[henri_espo]

Hello,
I'm using ESPOCRM version 5.4.3, on shared hosting environnement.
Current PHP version is 4.4 (!).
I've changed to 7.2 and got, in ESPOCRM "error 500". (same with 5.6)
I've checked ESPOCRM logs, empty.
As other applications (Drupal) installed on the same hosting worked properly after PHP upgrade, I wonder if some configuration should be changed in ESPOCRM.
Thanks in advance for support !

Hello,
Problem solved !
Context was shared hosting at OVH.
Solution was to select PHP instead of PHPCGI as engine.
Thanks and regards.
