Codeigniter 4 on shared hosting (NOT CPANEL)

Thank you very much. Its works as you suggested.

If you have a moment, can you please explain or suggest a link where I can find the problem with CI3's security that resulted in the change of folder structures. For as long as i have been using Ci3 I have never had a security issue so I am curious.

Also, as it is, without edited the .htaccess files, if you try to access to folders directly its displays the following message "Forbidden
You don't have permission to access this resource."

Is this not enough ?
