Newer versions of PHP are both faster and more secure. In fact, your version of PHP no longer receives security updates, which is why we sent you the notice.

Frequently Asked Questions

Which version should I update?
You should update your PHP version to 7.0 or greater (whatever the latest version is that is offered by your web host). Most sites can upgrade to PHP 7+ without issues, which is our recommendation.

How do I update?
Web hosts have the ability to update your PHP version. In most cases you can upgrade within your web hosting control panel or by submitting a support ticket to your host.
