Translate Site Interface

Hello!
How can I translate the strings of the site interface?
I have no edit-button on the “Translate Site Interface”-single-page.
There are also no .po-files inside my application/languages-directory. Just .mo-files.

Another question: How can I add new strings to the interface, when I use the t()-function in my theme?

Try going to /index.php/dashboard/system/multilingual/translate_interface

System & Settings > Multilingual > Translate Site Interface

I have no edit-button on the “Translate Site Interface”-single-page.

1st, You need to created empty site folder under application/languages/
Then, visit “Translate Site Interface” as TMDesign says
You click “Reload Strings” button on the top right,
Finally you will be able to start editing the translation

Another question: How can I add new strings to the interface, when I use the t()-function in my theme?

Same, once you added the t() strings in your theme, you go back to “Translate Site Interface” dashboard page, and click “Reload String”

It will scan all t() strings within application folder.

Thanks for your answer! It all works fine!
