How do I get po files to work in qa plugin?

Hey there! :slight_smile:

I just bought the qa plugin - which looks awesome. :slight_smile:
And I downloaded the po and mo files from https://premium.wpmudev.org/translate/projects/qa-wordpress-questions-and-answers-plugin/de/default

And put them into the languages folder inside the plugin folder. I even deleted to old .po file. But everything still shows up in english. How can I activate the use of the language files?

Thanks a lot! :slight_smile:
