Website displays white page after uploading Php site files to File manager

[darligee]

Please note that file manager works well.

Only that the PHP website doesn’t display also, it loads the favicon on the website properly.
I also ran the ran the below code to see if it works, because I normally do this in vestacp previous, which makes the website display.

sudo chown -R www-data:www-data public_html

find public_html -type d -exec chmod 755 {} ;

find public_html -type f -exec chmod 644 {} ;

sudo chmod -R 775 public_html/core/storage
sudo chmod -R 775 public_html/core/bootstrap/cache
sudo chmod -R 640 public_html/core/.env

But it still doesn’t display. Am new to HestiaCp

Which app are you trying to install?
Did you run the composer install?

[darligee]

No I didn’t.
I uploaded to file manager, I normally don’t do that when I do upload to vestacp or cpanel, am I supposed to do that here?

Also I ran composer install, as you suggested, and nothing changed
