Gravity Forms List Field Counter v1.4.0 has been released. This version requires PHP 7.4 or later, and is Gravity Forms 2.7 compatible.
The plugin now requires a minimum of PHP 7.4, although we’d recommend something more recent like PHP 8.0 or later. Even version 7.4 is old, obsolete, and unsupported now, so we won’t be supporting older versions than that any more.
Gravity Forms 2.7
You can update to the latest version from your WordPress plugin admin page. Here’s the full changelog for Gravity Forms List Field Counter.
