The only problem I've noticed was an error in language files (I've tried Italian and Russian)...
Here is it:
DEFINE( "ADSMANAGER_DEVICE", "€");
(...causes no price on Ad page...)
This bug is present in lang_italian_2_1_6.php and lang_russian_2_1_5.php (maybe somewhere else)
Here is the same const in lang_english and it's ok...
DEFINE( "ADSMANAGER_DEVICE", "$ %s");
%s - is important, let it stay! ;-)
More attention please! :-)
