Hi @lhawk,
We pull all the languages from ww.wp.xz.cn that have a complete WordPress installation available. If you check this list here: WordPress Polyglots Teams, you’ll notice that the Irish language doesn’t currently have a complete WordPress version available.
If a language isn’t included in our plugin, you can still make it available by adding a custom language in TranslatePress. To do this, go to TP Settings → Advanced tab, and use the Custom Language section: Add Custom Language. After adding the Irish language using the “ga” language code, you’ll be able to use it without any issues.
