Blank page on the web server

I uploaded my project to the web server, Following the security recommendations, I placed the codeigniter 4 files in the server's non-public directory:

Code:

/home/user/project

And in the public directory:

Code:

/home/user/public_html

I left the codeigniter's public archives:

index.php
.htaccess
robots.txt

In the index.php file, I set the path to the codeigniter's root directory:

PHP Code:

$pathsPath = FCPATH. '../project/app/Config/Paths.php'; 


After these settings I see a blank page!

What else should I do to make the system work properly?
