Hi,
You can manage your translation from Extensions->Language Manager->Overrider.
For example:
You can choose for a field a title like "GENDER"
in Language override you can createmany entry for GENDER constant
English GENDER->Gender
Italian GENDER->Sesso
Danish GENDER->Køn
Some constant is included into Easy Profile Languages files (USERNAME,NAME,LASTNAME,AVATAR)
To translate every parts of Easy Profile you can create your translation files:
copy this file /language/en-GB/en-GB.com_jsn.ini into /language/da-DA/da-DA.com_jsn.ini and translate it for front end
copy this file /administrator/language/en-GB/en-GB.com_jsn.ini into /administrator/language/da-DA/da-DA.com_jsn.ini and translate it for back end
