This document includes information about minimum requirements for our products and services. It also provides instructions on checking and updating your site’s PHP and WordPress versions.

To ensure that all the features of WPMU DEV plugins run smoothly on your site, we recommend running PHP version 7.4 or a later version. This also matches the WordPress minimum requirements.

Using a recent PHP version on your site is crucial as each release is supported for two years only. If your site is running an unsupported version of PHP, you’re probably missing out on important security and performance updates.
