incorrect function dwqa_get_latest_answer()

Hi,

You have function dwqa_get_latest_answer() in inc/status.php.

This function not work correctly!
You have this code in it:

function dwqa_get_latest_answer( $question_id = false ) {
	if ( !$question_id ) {
		$question_id = get_the_ID();
	}

	// When we get latest answer by normal query it take a long time to query into database so i will try to setup transien here to improve it. Of course we will use another cache plugin for QA site in additional
	$latest = get_transient( 'dwqa_latest_answer_for_' . $question_id );
	if ( false === $latest ) {
		$args = array(
			'post_type' 		=> 'dwqa-answer',
			'meta_query' 		=> array(
				array(
					'key' 		=> '_question',
					'value' 	=> $question_id,
					'compare' 	=> '=',
				),
			),
			'post_status'    	=> 'public,private',
	    	'numberposts' 		=> 1,
		);
		$recent_answers = wp_get_recent_posts( $args, OBJECT );
		if ( count( $recent_answers ) > 0 ) {
			$latest = $recent_answers[0];
			// This cache need to be update when new answer is added
			set_transient( 'dwqa_latest_answer_for_' . $question_id, $latest, 450 );
		}
	}

	return $latest;
}

$latest = get_transient( ‘dwqa_latest_answer_for_’ . $question_id ); return string 0 for some questions and not go to the condition because of Strict Equality Comparison (===). So it return string 0 in final!

And the post_status is public while it should be publish.

So please change if ( false === $latest ) to if ( false == $latest ) and 'post_status' => 'public,private' to 'post_status' => 'publish,private' to work correctly.

Thank you
