The plugin Drop Down List Field for Gravity Forms requires Gravity Forms to be i

I’m not sure whether my site/theme/whatever has automatically upgraded but this plugin has stopped working for me.

Displays a Warning in admin panel saying:

The plugin Drop Down List Field for Gravity Forms requires Gravity Forms to be installed.

Please download the latest version of Gravity Forms and try again.

Have downgraded theme and Gravity Forms and reinstalled this and other plugins but no luck.
