Hi,
to replace the date with location you would need to open a file wpadverts/templates/list-item.php and replace
<?php echo date_i18n( get_option( 'date_format' ), get_post_time( 'U', false, get_the_ID() ) ) ?>
with
<?php echo esc_html( get_post_meta( get_the_ID(), "adverts_location", true ) ) ?>
That being said the Location should on the [adverts_list] by default, however you are most likely using it in grid mode where the location is hidden and the date is shown, you can change that by adding the code below in wp-admin / Appearance / Customize / Additional CSS panel
.advert-item-col-2 span.advert-date,
.advert-item-col-3 span.advert-date,
.advert-item-col-4 span.advert-date {
display: none;
}
.advert-item-col-2 .advert-location.adverts-icon-location,
.advert-item-col-3 .advert-location.adverts-icon-location,
.advert-item-col-4 .advert-location.adverts-icon-location {
display: inline-block;
line-height: 1.8em;
padding: 10px 0 10px 0;
}
With the above CSS code you would not need to change the list-item.php file so the change would not be overwritten on the update.
