On April 9, 2024, we released MODX Revolution 2.8.7. This patch release of Revo 2, addresses PHP compatibility—especially with image previews across PHP 7.4 and 8.x. In addition to the PHP-related updates, a few other good old fashioned bugs were purged. The end result is a lot smaller error log and a much improved UX that content editors can enjoy.
If your site is running the 2.x version of of MODX Revolution, this should be considered a must-upgrade release—especially to ensure your site remains compatible with recent PHP releases.
