Currency

[shapwill]

Hi folks, I'm trying to change the currency symbol for my site's (PS 1.7.6.3) default currency (Romanian lei) when the site is viewed in English and German. Prestashop is using odd built-in defaults that make no sense for these languages ("lei" in English and "L" in German) and I'd like to change both to "RON". I tried the following suggestion found elsewhere on these forums, but it did not work:

<currency type="RON"> 
<displayName>Rumänischer Leu</displayName> 
<displayName count="one">Rumänischer Leu</displayName> 
<displayName count="other">Rumänische Leu</displayName> 
<symbol>RON</symbol> 
<symbol alt="narrow" draft="contributed">RON</symbol>
 <!--changed from "L"--> </currency>

I changed relevant section of de.xml (above) and also copied it into de_DE.xml, then re-installed German localization (using local data, not downloading from server) with "currencies" checked. Likewise with en.xml and en_GB.xml.  Reset cache, no change. 

Can anyone help?
