Hi,
The ECB does not give change rate for all currencies.
When a currency is not found, the function returns 1 (file convertECB.php , line 149&150)
It should return 0 to indicate that no conversion has been made. Otherwise the price written is wrong.
PS: I have posted in another section (probably the wrong one) concerning the currency Mexican Peso : it is not MXP, but MXN.
