I have installed the forum to my local sql express db. Version is 1,9,5 RC1. When I change Board's language English to Turkish, Login Button Text disappers in Turkish. I investigate from turkish.xml , Resource Name is "FORUM_LOGIN" and Localized Ressource is in Turkish "Forum Giriş". I mean it is true but in form , login button is small amd empty text.
Afterwards I have also change something in turkish.xml but changes dont apply to forum. When I change to another language , for instance german , login button text is ok. I think there should be bugs about turkish language settings. Please take a look.
