I have this problem when i try to make payment on vendor invoice.

**Warning** : A non-numeric value encountered in **/multicurrency/class/multicurrency.class.php** on line **564**

**Warning** : Cannot modify header information - headers already sent by (output started at /multicurrency/class/multicurrency.class.php:564) in **fourn/facture/paiement.php** on line **346**

I use Dolibarr V12.0.4 in MKD currency.

Hi,

What PHP version do you use ?

You can also silence the PHP warnings in the PHP configuration
