Pages do have Custom Fields enabled by default on WordPress. If you’re not seeing them on the “New/Edit Page” page, then check the “Screen Options” pull down tab on the upper right corner of your Dashboard. See if “custom fields” is checked.

I emphasized into the loops, as Deckster0 said in WordPress support that, the_content() works only inside a WordPress Loop. I’m placing these code into a … Read more
Use has_nav_menu(), and test for theme_location, rather than menu_id: <?php if ( has_nav_menu( $theme_location ) ) { // User has assigned menu to this location; // output it wp_nav_menu( array( ‘theme_location’ => $theme_location, ‘menu_class’ => ‘nav’, ‘container’ => ” ) ); } ?> You can output alternate content, by adding an else clause.

I usually use this approach: wrong approach <?php query_posts( array( ‘category_name’ => ‘news’, ‘posts_per_page’ => 3, )); ?> <?php if( have_posts() ): while ( have_posts() ) : the_post(); ?> <?php the_excerpt(); ?> <?php endwhile; ?> <?php else : ?> <p><?php __(‘No News’); ?></p> <?php endif; ?> With the help of @swissspidy the correct way is … Read more
Use get_posts() and the parameter name which is the slug: $page = get_posts([ ‘name’ => ‘your-slug’ ]); if ( $page ) { echo $page[0]->post_content; } Be aware that the post type in get_posts() defaults to ‘post’.
