Code crash when $price is “false” in wmc_revert_price(functions.php – 176)

I have to change from

return $rate ? $price / $rate : ”;

to

return ($rate && $price!=”false”) ? $price / $rate : ”;

to get website back on. Seams that its not handling $price good when it for some reason is text(!)…

Talking about this function:

function wmc_revert_price( $price, $currency_code = ” ) {
if ( ! $price ) {
return false;
}
$setting = WOOMULTI_CURRENCY_Data::get_ins();
$current_currency = $setting->get_current_currency();
$currency = $currency_code ? $currency_code : $current_currency;
$rate = wmc_get_exchange_rate( $currency );

return $rate ? $price / $rate : ”;
}
