How do I fix the_content was not found?

So apparently randomly my blog page has stopped recognising or displaying the post grid formatting (An ‘Essential Addons’ For elementor block)

I tried this scenario thinking if I created a template in Elementor it wouldn’t whinge as much – I was wrong, nothing changed:

Create and save a template in Elementor.

Add page

Edit with Elementor

Add title and post grid.

Preview – all good.

Save

Exit to dashboard

View on live site – Duff.

Back to Dashboard-

Pages > Edit with Elementor > starts to load and then I get this
[![the_content was not found on your site][1]][1]

When I updated Elementor a few weeks ago it crashed the site (imagine my surprise) I edited the plugin with a code suggestion from here and that seemed to resolve it.

Yesterday I noticed that blog posts were no longer formatted as tiles/grid format and just display as full text on a continuous page.

Below is my Archive.php code, Where/how can I insert the_content into this file? is that even the resolution?

    get_header();

    $sb = ingenious_get_sidebars();
    extract( $sb );
    $page_classes = "";
    $page_classes .= !empty( $sb_layout_class ) ? " {$sb_layout_class}_sidebar" : "";
    $page_classes = trim( $page_classes );

    $posts_grid_atts = array(
            'post_type'         => 'post',
            'links_enable'      => true,
            'total_items_count' => PHP_INT_MAX
    );
    if ( is_category() ) {
        $term_id = get_query_var( 'cat' );
        $term = get_term_by( 'id', $term_id, 'category' );
        $term_slug = $term->slug;
        $posts_grid_atts['tax']     = 'category';
        $posts_grid_atts['terms']   = $term_slug;
    }
    else if ( is_tag() ) {
        $term_slug = get_query_var( 'tag' );
        $posts_grid_atts['tax']     = 'post_tag';
        $posts_grid_atts['terms']   = $term_slug;
    }
    if ( is_date() ){
        $year = ingenious_get_date_part( 'y' );
        $month = ingenious_get_date_part( 'm' );
        $day = ingenious_get_date_part( 'd' );
        if ( !empty( $year ) ){
            $posts_grid_atts['addl_query_args']['year'] = $year;
        }
        if ( !empty( $month ) ){
            $posts_grid_atts['addl_query_args']['monthnum'] = $month;
        }
        if ( !empty( $day ) ){
            $posts_grid_atts['addl_query_args']['day'] = $day;
        }
    }

    echo "<div id='page'" . ( !empty( $page_classes ) ? " class='" . esc_attr($page_classes) . "'" : "" ) . ">";
        echo "<div class='ingenious_layout_container'>";
            if ( in_array( $sb_layout, array( "left", "both" ) ) ){
                echo "<ul id='left_sidebar' class='sidebar'>";
                    dynamic_sidebar( $sidebar1 );
                echo "</ul>";
            }
            if ( $sb_layout === "right" ){
                echo "<ul id='right_sidebar' class='sidebar'>";
                    dynamic_sidebar( $sidebar1 );
                echo "</ul>";
            }
            else if ( $sb_layout === "both" ){
                echo "<ul id='right_sidebar' class='sidebar'>";
                    dynamic_sidebar( $sidebar2 );
                echo "</ul>";   
            }
            echo "<main id='page_content'>";
                echo ingenious_sc_blog( $posts_grid_atts );
            echo "</main>";
        echo "</div>";
    echo "</div>";

    get_footer();
?>```

Any help much appreciated.

Thanks
