Future versions of phpShop-for-MOS will support Mambo's SEF mode (you can see the SEF mode and phpShop in action at this site). Therefore some major changes have been done to page parsing. The page parameter, formerly submitted as (e.g.) page=shop/browse, will now be submitted this way: page=shop.browse
As it seems today, RC3 will be released at the end of next week. I will contact all translators and ask them to translate the new english lines in their language file.
