How to do single column on blog page but multiple columns on category archives?

Hi there,

We would need to use a filter as seen in the example here:
https://docs.generatepress.com/article/using-columns-in-the-blog/

Is the blog page also your front page?

Let me know :)

yes Leo, blog page is the frontpage

I somehow solved this thru loop template leo, thanks.

Glad to hear that you've found a solution.

Just FYI you don't actually need the loop template with Query loop for this.

If the columns option is activated in the customizer, you can just use this snippet to turn it off on the blog/front page:

add_filter( 'generate_blog_columns', function( $columns ) {
    if ( is_front_page() && is_home() ) {
        return false;
    }

    return $columns;
} );
