Hi Matthew,
Thanks for posting. Any chance the language translation you did could be added to the main plugin? We are always hoping to expand our translations.
To use your new .po file, add it to the plugins /lang folder. You’ll need to have a translation for each of our plugins you’re using. Make sure you also add the corresponding .mo file, and that the files follow the naming convention of the other .po/.mo files and have your language’s suffix (ex. fr_FR).
The next thing is to change the language code in your wp-config.php file. If you’re not familiar with doing that, you can follow the instructions here.
Let me know if you have any trouble and I’d be happy to help out 🙂
Best,
Leah
