If you are on shared hosting, chances are that the fileinfo PHP extension is either not enabled or installed.

In the case where it's not enabled, navigate to the Software section of CPanel (consult documentation of your control panel if you're not using CPanel) and click Select PHP Version (or something related to that) and enable the extension by checking its box and saving your action.

If it's not installed, the extension won't be part of the PHP extensions at cPanel > Software > Select PHP Version > Extensions, edit your php.ini file and uncomment extension=php_fileinfo.dll if you're on Windows. Consult your hosting provider's docs if any of these don't work.
