Page displays 'index.php'

Basic install of CI4 works, producing CodeIgniter4 page.
Followed User Guide First Web Site instructions - page displays text 'index.php'
Tried another new install, added new function to Home.php controller to echo a simple string - no change.
Tried controller to view call. No view displayed still only 'index.php'
I have PageNotFoundException setup. Is my display the output from the PageNotFoundException? I'd have expected more than that.

Clearly, I've got something wrong, but where?

Changed two items in Config/App.php - baseurl and index.php removal.
Followed Routes.php changes as instructed.
Changed apache config files, created sites-available conf file for site.

App/Config/app 

PHP Code:

public string $indexPage = 'index.php'; remove index.php 


Codeigniter First, Codeigniter Then You!!

Thanks
Done that.
And set the Base-URL line too, as I mentioned in my original message.

This is the tutorial I followed.

Where did you go in that tutorial?
What did you do? and what did you get?

Upon running, the page shows index.php as text

How did you access the page exactly?
The exact URI?

Sorry for the delay in replying, I've reloaded the operating system and all software and am documenting every move so that I can (hopefully) repeat it.
Having followed the tutorial, I was using www.[mywebsite]/home.
Interestingly, I have brought up the same error while setting up a new codeigniter4 instance and working through the various settings, e.g.$BaseUrl, CI_Environment etc.
And I can repeat the behaviour.
Current uri: www.[mywebsite]/public/index.php
Current settings:
sites-available/[mywebsite].conf - DocumentRoot -> /var/www/html/[mywebsite]/public
Directory -> /var/www/html/[mywebsite]
$BaseURL=www.[mywebsite]/
$IndexPage='index.php'
.env CI_Environment Development
Codeigniter4 download into user folder then copied to /var/www/html/[mywebsite]
ownership of website directories is www-data:www-data and my user is in the www-data group. I can edit files without sudo.
Access currently set to 775 throughout - yes far too much, but I want to get things working without permissions getting in the way.

www.[mywebsite]/public/index.php - shows index.php as text string
www.[mywebsite]/public/ - shows index.php as string
www.[mywebsite]/index.php - shows Codeigniter4 welcome page
www.[mywebsite]/ - shows Codeigniter4 welcome page

I have created nothing in the way of web content yet.
Clearly my problem was incorrect setup, but where?

Your last 2 lines are the expected behavior since your DocumentRoot is correctly set to the public directory. I would have expected referencing home or public to generate route errors. That initial index.php in the public folder is just a controller to start up the Codeigniter framework.
