Codeigniter 3 problem on vps


I followed the installation guide on and it was great. Thank you so much for the detailed guide. However, I am facing an issue when trying to install my CodeIgniter script. It is working fine on another hosting, but not on the VPS that I installed CyberPanel. Could you please help me with this issue and suggest what could be the reason behind it?

Error is;

on the website page :

Your /home/ file does not appear to contain a valid configuration array.
