edit layout templates

First of all, You are now using old generation mode.
I recommend change to Generation 3 from
Appearance > Customize > Lightning Function Setting.

But… Generation 3 don’t have front page widget area that, you have to some changes.

1. Please take a full backup with tools such as UpdraftPlus plugin before making any changes.
2. Install and activate plugin VK Block Patterns
3. Move to the front page ( post ) edit screen
4. [ + ] -> Patterns -> PR Content -> Column Icons and modify it.
5. Change to Generation 3 from Appearance > Customize > Lightning Function Setting.

6. Appearancr > Customize > Additional CSS

In case of Generation3 ( all pages )

.vk_posts.next-prev{ display:none; }

In case of Generation3 ( one column only )

.main-section:where(:not(.main-section--col--two))  .vk_posts.next-prev{ display:none; }

In case of Generation2 ( one column only )

.mainSection-col-one .vk_posts.postNextPrev{ display:none; }

In case of Generation2 ( all pages )

.vk_posts.postNextPrev{ display:none; }

edit what is show on the sidebar in the 2 column.?

Put the VK Post List widget or VK Taxonomy list widget and so on

Appearance > widget > sidebar(post)

Excellent, thank you!
