When upgrading to PHP 7.4.24 which is the latest stable version of 7, I’m getting the following issues. Is there a known compatibility issue with this version of PHP?
Gravity Forms is fully compatible with PHP 7.4+ and PHP 8.
Those issues look like they are caused by a caching and/or optimization plugin/service. I recommend clearing/flushing their caches and your browser cache.
