Space between amount and currency symbol

Hi,

you should be able to do that by adding the code below in your theme functions.php file or even better by creating a new blank plugin (https://wpadverts.com/blog/how-to-use-code-snippets-in-wordpress/) and pasting it there

add_filter( "adverts_currency_list", function( $l ) {
    $space = array( "EUR", "PLN" );
    foreach( $l as $k => $a ) {
        if( in_array( $a["code"], $space ) ) {
            $l[$k]["sign"] = " " . $l[$k]["sign"];
        }
    }
    return $l;
} );
