What potential issues may arise if the file_uploads setting is off?

If the file_uploads setting is off in the PHP configuration, users will not be able to upload files through a form on your website. To solve this issue, you need to enable the file_uploads setting in the php.ini file or use the ini_set() function in your PHP script to dynamically enable file uploads.

// Enable file uploads in PHP script
ini_set('file_uploads', '1');
