Adding new translation issue

Hi to all,

I want to add new translation. So I followed wiki : /display/FOP/Translating+FreePBX+Manually
New language is added to language bar, but when I select it, nothing really changes.
What is the problem?! Can you please give some hints ?

Thank you.
Regards.

are you sure your po/mo files are good?

I used Poedit tool for translation and msgfmt tool for output files.
Are there other steps for translation that may I missed them?

It should be much simple. Poedit will generate a mo file, you can insert into your location.
