Was just “playing” with the languages in the kurviger website. There at some elements is no translation to greek. See marking in the screenshot:
“Deine Routen”-button, “Favoriten”-button, “Tourcode”-button, “web.save_as_new_route”-button.
At the “import” and “export” buttons the tooltips are in german instead of greek.
Would be nice if this bug could be corrected.
