You should be able to set all your kwrite prefs back to default by doing:

rm ~/.kde/share/config/kwriterc

I'm running kwrite 4.11.1.  I've attached a screenshot of where I find 
highlighting on mine.  Perhaps you have an older version that either 
doesn't have the option, or it's in another location.
