Dazzling won't install in Russian.

Good day,
I checked, there are ru_ru.po and ru_ru.mo files in languages folder. My wordpress is in Russian, and previous themes I tried automatically started in Russian. I added a line define(‘WPLANG’, ‘ru_Ru’); to wp-config file (WPLANG file wasn’t there before at all). Tried define(‘WPLANG’, ‘ru_ru’);, just to be sure.
Nothing works. Dates, comment forms appear in Russian, but buttons etc is still in English.
How do I resolve this problem?

Hi @entoursis,

I hope you are well today and thank you for your question.

Please make sure that you have translated the theme in Russian as described on the following page.

Best Regards,
