Dear @alimir
Thanks for the reply! Your tip guide me to the right direction.
I am now able to return WP_Query object for Most Liked Post.
But I’m unable to get the new parameter is_normal to works. I’m not sure what is the supposed intended behaviour, however I manage to return posts with 0 like with post__not_in argument and merge the 2 WP_Query object together.
Also just to point out, in case you didn’t notice, there is a typo for is_normal variable.
Thanks for your time. Cheers.
