I'd set up the Events Category Colors plugin which was working exactly as expected; different categories had different colours set etc.
I've updated to The Events Calendar and The Events Calendar Pro and now all the different events (in different categories) are using the same colour (blue).
Additionally, the previous / next (week) links don't load any colour, but if you refresh the page the same blue colour loads for all posts.
Am I missing a setting somewhere or could this be a bug?
You can see an example of this here: http://squeakygatestg.wpengine.com/calendar/
Thanks in advance for any help!
