I’m having this error. It appears as I access the integration with WP fusion.
Any ideas?

: Undefined array key 0 in**/home/c2460615/public_html/wp-content/plugins/gravityforms/includes/settings/class-settings.php** on line1456

This is a bug in WP fusion, they have defined their form settings as an associative array instead of the indexed array Gravity Forms requires.
