For theme version after 1.30.6

Replace in libs/help_functions.php the code as in the screenshot

 

Original code

$property_lot_size = wpestate_get_converted_measure( $post_id, 'property_lot_size' );

Modified code

    $property_lot_size = floatval( get_post_meta($post_id, 'property_lot_size', true) );

    if ($property_lot_size != '') {  
$property_lot_size = wpestate_sizes_no_format($property_lot_size) . ' '.__('ac','wpestate');
    }

NOTE: The multi-size widget cannot apply now for lot size after this code edit.

Below help applies for theme version 1.30.5 or older

This change would have to be done in code because by default we have 1 measurement system.

Go to libs/listing_functions.php

Go to this code:

if ($property_lot_size != '') {
$property_lot_size = wpestate_sizes_no_format($property_lot_size) . ' '.$measure_sys.'2';
}

meas

change to:

if ($property_lot_size != '') {
$property_lot_size = wpestate_sizes_no_format($property_lot_size) . ' '.__('ha','wpestate');
}

measure

Replace “ha” with acres what any other word you wish.
