Popular Post By Month in WordPress

I’ve tested your code on my installation and it is working just fine. So the code in not an issue.

There are two possible reasons why this is not showing any posts.

1) You do not have any posts for that month 🙂

2) You haven’t any metadata ‘wpb_post_views_count‘ in database so it returns nothing.

For debugging you can simply check if you have posts with current month published date.

If yes, then comment out ‘meta_key’ => ‘wpb_post_views_count’,
and ‘orderby’ => ‘meta_value_num’, lines to check if any post is returned and see if missing metadata was causing this issue.

Cheers!
