WARNING: WordPress core is not yet compatible with PHP 8.1. Many themes and plugins are currently incompatible as well. We strongly recommend testing thoroughly on staging before switching any of your production sites to PHP 8.1.
SpinupWP now supports PHP 8.1. WP-CLI has been updated on all customer servers to version 2.6.0, which introduces PHP 8.1 compatibility.
You can now select PHP 8.1 when creating a new site and update existing sites to use PHP 8.1 via the SpinupWP dashboard. From a site’s dashboard, select “Settings” on the left menu, then select the version you want from the PHP dropdown menu.
