Magento allowed currencies list

Question

In my Magento backend, I am not seeing any allowed currencies beyond the 3 I have already set up. Any ideas why?

Answer 1

The list of possible currencies ultimately comes from the many XML files in /lib/Zend/Locale/Data, in particular root.xml is always consulted. Check this folder exists and contains about 400 or more of these files. Also, check they are all readable to web user on your server.

_{The file \app\code\core\Mage\Core\Model\Locale\Config.php is probably only used for default values during installation or setup.}
