Showing Expiration Date

Hi,
by default there is no such option, but you can display the expiration date on the Ad details page below the location by adding the code below in your (child) theme functions.php file

add_filter( "adverts_tpl_single_details", function($post_id) {
    ?>
    <div class="adverts-grid-row">
        <div class="adverts-grid-col adverts-col-30">
            <span class="adverts-round-icon adverts-icon-calendar"></span>
            <span class="adverts-row-title"><?php _e("Expires", "wpadverts") ?></span>
        </div>
        <div class="adverts-grid-col adverts-col-65">
            <?php $exp_time = get_post_meta( $post_id, "_expiration_date", true ); ?>
            <?php if( $exp_time ): ?>
            <?php echo date_i18n( get_option( "date_format" ), $exp_time ) ?>
            <?php else: ?>
            Never
            <?php endif; ?>
        </div>
    </div>
    <?php
} );
