What are some common troubleshooting steps for resolving "Forbidden" errors when using mod_rewrite in PHP?

When encountering "Forbidden" errors while using mod_rewrite in PHP, it is often due to incorrect file permissions or configuration settings. To resolve this issue, ensure that the .htaccess file is properly configured with the correct rewrite rules and that the necessary permissions are set for the file and directory.

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
</IfModule>
