Installation Problems on Synology Drive

Hi there.

I am trying to install CI 4 on my Synology drive for testing.

I have installed the package at

http://192.168.***.***/test.domain.co.uk/ci_smr/

When I try to access the site via

http://192.168.***.***/test.domain.co.uk/ci_smr/public/index.php

I get an ERROR 500 message and this message in the Apache log file:

Got error 'PHP message: PHP Warning:  require_once(/Config/Constants.php): failed to open stream: No such file or directory in /volume1/web/test.domain.co.uk/ci_smr/system/bootstrap.php on Line 79

Failed opening '/Config/Constant.php'

The base url is set to:

public $baseURL = 'http://192.168.***.***/test.domain.co.uk/ci_smr/';

Can anyone shed some light on this?

Thank you.

JB
