I have Kubuntu 16.04 installed. My recollection is that automatic spell checking was working fine under Kubuntu 14.04, with all the misspelled words it found underlined. But now since I've upgraded, it doesn't…
Under the Configure-Kate-dialog, I have selected a bright red line for Fonts & Colors [colors tab] spelling mistake line so it should be visible. And under that dialogs Editing section, within the Spellcheck tab, I have selected [x]Automatic spell checking enable by default, to no avail. And I've tried toggling on and off this other option under the spellcheck tab [x]Automatic spell checking enabled by default, and [x]Enable auto-detection of language, to no avail.
Outside of the configure-kate-dialog, under the main menu's TOOLS>spelling> [x]automatic spell checking has been toggled on and off, to no avail. Any ideas what's going on?

I found several reports of this bug. Listing here, here and here.
However, there is a workaround. You need to disable Enable autodetection of language from Settings -> Configure Kate -> Editing -> Spellcheck tab.
Then it will detect the error if you go to Tools -> Spelling -> Spelling. But auto-detection doesn't work sometimes. You can make this menu a shortcut by using Settings -> Configure Shortcuts menu.
