Missing osclass language file at sourceforge

[lenin]

Hello, dears

I am new to Osclass. I like it very much. I have run a listing site with this script. Working very nicely. You can see at https://bnlist.com

The problem is now I want to add the multilingual option with the Bengali and English language. But https://sourceforge.net/projects/osclass/files/Languages/ there is no Bengali language.

If I want to translate the theme's language file, will it work?

The backend not necessary to translate in Bengali. I need only translate frontend in Bengali.

I have no idea from where I should start. Plz help me.

Thanks in advance.

Kind Regards
Moktadir Rahman
