- good all is fixed now (yeah - I often come in here... so I just tried to help where I thought might be able to, as saw some of your posts were not answered).
To be honest I am still wondering if LC_ALL will actually work - as another V4.2.X person I helped used that with no problem on there store (so wondering if it was just the quotes issue before for you//. or if the changing to Greek for default language means LC_ALL doesn't work properly).
Anyway... - the main thing, is that your store works well in Greek now (which is great!) and my post has been corrected thanks to your coments (so should help others later)... haha - thanks and cheers, Asiaplay
