Codeigniter 4 on shared hosting (NOT CPANEL)

You can place the content of /public alongside app, system, writable... and modify your index.php into:

PHP Code:

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


You now got the same security as your CI3, and need to protect it in other ways, with e.g. htaccess, so people don't have access to the application part of the code.
