this code:

if ( $data) {
				$unserialized_data = unserialize( $data );
				if ( isset( $unserialized_data['iwp_action'] ) ) {
					$iwp_action = $unserialized_data['iwp_action'];
				}

…. my bugfix:

if ( !empty($data) ) {
				$unserialized_data = maybe_unserialize( $data );
				if ( isset( $unserialized_data['iwp_action'] ) ) {
					$iwp_action = $unserialized_data['iwp_action'];
				}
			}
