Documentation, Reference Materials and Tutorials for WPForms
WPForms and WP Mail SMTP by WPForms both currently requires PHP version 5.3 or higher.
If you were linked to this page from your WordPress dashboard it’s because we noticed that you’re running an outdated version of PHP.
PHP is the programming language that WordPress and WPForms are built on. The version that is currently used for your site is no longer supported. 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.
Which version should I update?
You should update your PHP version to either 5.6, 7.0 or 7.1. On a normal WordPress site, switching to PHP 5.6 should never cause issues. 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.
