CSS in new calendar theme – All in One Events Calendar

Hi there,

I’m currently trying to set up a custom theme for All in One Events Calendar. I’ve placed my theme, based on the Gamma theme, in wp-content/themes-ai1ec/[my-theme] and applied it.

However, though I have added a new override.css inside the CSS folder of that theme, as suggested in the user guide, it doesn’t recognise the file or the style rules I have included.

Do I need to somehow ‘register’ this file, perhaps in my site’s functions.php, or should All in One Events Calendar be recognising it automatically?

I’m certain this is a very simple problem, but I’d be grateful for your help. Thank you!
