This fix replace your comment count to go with most of central european languages. There was a gap when word “Commments” was the same for counts greater than 1. But for example in Slovak and Czech there is different word when count is from 2 to 4. So there was gramatical error. This will fix it.
This plugin is made for Slovak, Czech and other slovanian languages. If you are using different language on and you have similar problems but with other numbers, just write me to firstname.lastname@example.org.
