Fixed price issue

Hi,

I’m having issues with the Fixed price formatting. I have two currencies set up – CZK as the main currency and EURO. I checked the fixed price option, but when I add the euro price, I receive the following errors

Warning: A non-numeric value encountered in /www/doc/www.marianrehak.com/www/kutulu/wp-content/plugins/woocommerce-multi-currency/includes/functions.php on line 134

When I update the rates, the error disappears, but wrong price is shown by the product. Also, the Total price in euros gets rounded up even though there is no rouding set up anywhere in the plugin or the theme.

Thanks for your help
