I cannot reproduce this.. Could you provide more information about the steps you took? does it happen in any other language at all?
I followed the installation steps as you provided...
Just found out if i change the style configurator to default it seems to work find, but if i change it to anything else then it will all be highlighted white
yes, the same for me, i'm using not the default theme, but a dark one. and then code is highlighted
This is really a notepad++ issue. Problem is styles aren't global for different types, and need to be set per language per theme. You'll need to edit the ColdFusion settings in the Style manager to match the style of your choice (or update the colours in nppColdFusion.xml)
