PHP 8.1 is live

Update: The scheduled upgrade to PHP 8.1 was successful. If you encounter any issues, please contact webservices@princeton.edu.

We have scheduled the upgrade for our managed WordPress platform to PHP 8.1 on Tuesday, May 2, 2023. This is a major upgrade from PHP 7, with some significant compatibility issues with older plugins and themes.

PHP 7 is officially unsupported by the PHP community, but our hosting partner continues to provide extended long-term support for this older version.

We have been testing extensively for a few months, and we are confident that most issues are resolved. However, site owners may need to contact webservices@princeton.edu if they experience any issues after the PHP upgrade.
