Forbidden You don't have permission to access / on this server (Laravel)

The application was working fine on my local pc but when I transfer the files to web hosting it’s giving 403 Forbidden Error.

Can anyone tell me what I am doing wrong?

You need to rewrite your / directory to /public. Add a .htaccess file to your installation/root directory with the following content.

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteCond %{REQUEST_URI} !^public
    RewriteRule ^(.*)$ public/$1 [L]

All it does is redirect everything to /public.
