I have found slovenian translation, in fact instalation of smf 1.1 rc3. After instalation you can choose between slovenian or english. But in slovenian there is no verification picture and there is missing text. You can see it here: here (http://zvrzina.net/tabla/index.php?action=register)
How can I solve this? Which files should I change and of course how?
Do an ASCII compare of English and Slovenian files and add the 1.1.1 lines that are missing in Slovenian. You can translate them later.
Which files? All of them?
It's best to do them all as other strings might be missing in other screens.
See in priority (for verification)
Login.english.php
Errors.english.php
ModSettings.english.php
PersonalMessage.english.php
and their corresponding Slovenian files ror 1.1 RC3.
I'll update all files to 1.1.1. Please PM me an email adress where I can send you the files. :)
