WordPress Post Thumbnail not Shown via WhatsApp Share

Bismillah. I manage several websites using WordPress. klikmu.co is the most recent one. We use a theme named newspaper-X.

I faced a weird problem: When a post shared via Facebook, a featured image is shown and previewed by default. But when it is shared via WhatsApp, the image is not shown and replaced by a static web icon. Any different post I have shared via WhatsApp are always accompanied by the static web icon. It is really weird thing. This problem really stuck in my mind for two days.

I used WP Responsive Recent Post Slider plugin in my wordpress, after I put code [recent_post_slider] as text widget for Home/Front page, the slider did not shown anything except the code [recent_post_slider] itself. But, when I put the code as a post content, and then I view the post, the slider is visible correctly.
