Hello Alfred,

I am really sorry for the delay of this reply as it is a weekend for us here.
It seems like we missed up the language string about "Rate this item", but you can temporary add this language string in your file, we will including this in next release version of Komento.

JoomlaFolder\language\en-GB\en-GB.com_komento.ini
//Add this language string in below

COM_KOMENTO_RATING_THIS_ITEM="Rate this item :"

JoomlaFolder\components\com_komento\themes\kuro\comment\form\ratings.php
LINE 25

Replace with

Hope this help.
