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?
