I am running the upgrade https://erp.nmc.go.ke/install/upgrade.php?action=upgrade&selectlang=en_US&versionfrom=16.0.0&versionto=17.0.0
and getting the error below.
This page isn’t working
erp.nmc.co.ke is currently unable to handle this request.
HTTP ERROR 500
It has been working so well until I tried the upgrade.
Kindly guide on how to resolve.
