WooCommerce Andreani
Plugin link: https://shop.wanderlust-webdesign.com/shop/woocommerce-andreani-premium-shipping/
Note: 25-09-2020 this fix was implemented by author of the plugin directly into the plugin “WooCommerce Andreani”
In file wp-content\plugins\wanderlust-andreani-shipping\includes\class-wc-shipping-andreani.php add next code:
if (class_exists('WOOCS')) {
global $WOOCS;
$currencies = $WOOCS->get_currencies();
if (isset($currencies['ARS'])) {
$precio = $WOOCS->back_convert($precio, $currencies['ARS']['rate']);
}
}
This only works if the base currency is not ARS
