Hi!
I like the widget “Unite: Popular Posts Widget”, but it’s not possible to translate “Popular” and “Recent” tabs on pot file. I’ve created a pt_BR.po file to translate some terms which were not automatically translated to Portuguese, but those tab captions were not found.
Am I mistaken?
Thanks!
This was actually problem with theme translations files.
I have now updated missing string to default theme translation files and you can download updated theme fron Github. It will take a while untill theme will be available from WordPress.org via automated update.
I updated the theme, but now the “Popular” and “Recent” tab captions don’t show up. 
I made a really stupid mistake there. Thank you for pointing that out!
Please download theme from Github again and it should now work properly.
Sorry for my inconvenience!
Yes, now it works! 
Thanks!
If you decide to translate this theme completely it would be great if you could send me translation files, so I could add them to default theme installation. I would really appreciate it!
Also I keep the track of all our contributors and you will be featured on our contributors page as well. You can see it here: Our Contributors and Theme Translators - Colorlib
Thank you!
