I’m very pleased (and grateful) for the efforts of user “Łukasz” in updating the translation of all kiwitrees texts to Polish.
It’s based on the current 3.3.9 release, but not included in the download package for that version. It will be included in the 3.3.10 release, but for anyone wanting to include it now you can download it from this topic.
Simply download the zip folder attached below here, extract the file po.mo, and copy it to your kiwitrees/languages folder on your web server (replacing the version currently there).
Then log in to your site, visit the page Administration > Site administration > Clean up, and delete the “cache’ folder. Job done!
