Following Static pages tutorial - No input file specified.error

Hi everyone

I'm new to codeigniter and I'm trying to install directly onto a live domain on a shared hosting server. 
 
Installed using composer. following the guide here: https://codeigniter4.github.io/userguide...poser.html
public files are in the public_html directory. Everything else is one level up. 

The welcome page loads correctly here: https://codemechanic.co.uk/

I'm now following the guide here: 
https://codeigniter4.github.io/userguide...pages.html

I've followed all steps correctly up to "Running the app" 

When I go to any of the addresses specified I receive the error "No input file specified." eg here: https://codemechanic.co.uk/pages

I don't understand why this is. I've done some googling but can't find a solution.
Things i've tried.

changing the .htaccess file in public_html:

Code:

RewriteRule ^([\s\S]*)$ index.php/$1 [L,NC,QSA]
changed to:
RewriteRule ^([\s\S]*)$ index.php?/$1 [L,NC,QSA]

this changed the error to a 404 when visiting https://codemechanic.co.uk/pages

I've also changed the baseURL to https://codemechanic.co.uk/ to in app/Config/App.php - no changes there. 

Does anyone have any suggestions?

You should enable development mode:

Most likely you pages controller are named pages.php and not Pages.php. Due to the fact it's not a rewrite problem, as index.php url aren't working.

Thank you for the quick reply. Controllers page is named Pages.php, and env file is set to development. So no problems there. Controller set up like so:

Hi, you need to have a "." in front of your "env" for it to be able to work.

Now:
env

Should be:
.env

Pages look OK thought.

OK thanks. Corrected that, named .env 

https://codemechanic.co.uk/pages returning a 404 when htaccess is set to :
RewriteRule ^([\s\S]*)$ index.php?/$1 [L,NC,QSA]

or "No input file specified." when set to:
RewriteRule ^([\s\S]*)$ index.php/$1 [L,NC,QSA]

Keep a ? in there, that are server specifics. Open up your writable/logs and see what errors you have.
Have you disabled the auto route in /app/Config/Routes.php?

Should be:

PHP Code:

$routes->setAutoRoute(true); 


OK, will keep the ? in there. 

no change to auto route. Only change to this file was adding the (:any) route:

Can you try and reverse those $routes->get() and put / one after (:any)?

Like this? still returning 404.

Yep, but apparently that made things worse. So go back again. Check your writables/logs folder for tips.
