Inside “gravity-forms-bootstrap-style.php” add “__FILE__” to the plugins_url call.

Before:
wp_register_style( 'gravity-bootstrap', plugins_url('gravity-forms-bootstrap.css'), array(), '1.0', 'all' );

After:
wp_register_style( 'gravity-bootstrap', plugins_url('gravity-forms-bootstrap.css', __FILE__), array(), '1.0', 'all' );
