Netbeans mark occurrences highlight stopped working

Question

I've been using this awesome Netbeans feature for a long time now and I got pretty used to it. When you select a variable/function/whatever it is supposed to highlight all it's other occurrences but my Netbeans stopped doing that. I can however scroll through the occurrences with ALT + UP or ALT + DOWN, so the feature is working, but I just don't see the highlight.

Also, I am missing the categories from Tools/Options/Fonts&Colors/Syntax

Answer 1

• Try to run your NetBeans installation with a clean user dir http://wiki.netbeans.org/FaqWhatIsUserdir
• Try a different syntax highlighting theme.
