Layout of homepage automatically changed

I have been directed here from the WordPress.com forum.

Hi, two days ago, the homepage changed on this blog: https://www.bonsaimotorworld.com

Before, under the slider, listed a summary of recent posts and there were about 5 widgets on the left sidebar. Now this is all gone.

I can still see these widgets under Dashboard-> Appearance-> Widgets. My posts are still accessible by using the menu on the blog or clicking the links in the slider.

I tried playing around with in Settings-> Reader, but no luck. I have also searched the forums for answers, but can’t seem to fix it. Please help me to get the homepage back as before?

The blog I need help with is bonsaimotorworld.com. It is an adventure (organic) theme.
