CI4 not loading after fresh install — blank page on localhost Post:

I’m trying to set up CodeIgniter 4 on my local dev machine (Ubuntu 22.04, PHP 8.1) for a side project — a fresher job board I’m working on: https://247uaefreshers.com.
I followed the official CI4 install guide using Composer, no issues during setup. But when I navigate to

Code:

localhost:8080

, I just get a blank white page — no error, no logs, nothing in the browser console either.
I’ve tried:
• Running

Code:

php spark serve

(starts fine)
• Double-checked

Code:

.env

settings
• Permissions on writable/ seem okay
• Tried adding basic echo in

Code:

app/Controllers/Home.php

— still blank
Anyone seen this behavior before? Wondering if I missed something basic. Appreciate any tips ?
