<div class="container">
    <?php
    // set up or arguments for our custom query
    $paged = ( get_query_var('page') ) ? get_query_var('page') : 1;
    $objekte_args = array(
        'post_type' => 'objekte',
        'posts_per_page' => 1,
        'paged' => $paged
    );
     ?>
        <?php $objekte = new WP_Query( $objekte_args ); ?>
        <?php if ( $objekte->have_posts() ) : ?>
        <?php while ( $objekte->have_posts() ) : $objekte->the_post(); ?>
        <div class="row">
            <div class="col-md-push-1 col-md-4">
                <h2>
                    <?php _e( 'Objekte', 'ryvola' ); ?>
                </h2>

                    <?php the_content(); ?>
                </div>
                <?php echo paginate_links( array(
                    'format' => '?paged=%#%'
                )); ?>
            </div>
        </div>
        <?php endwhile; ?>
        <?php wp_reset_postdata(); ?>
