I find myself facing an extremely basic problem which I cannot seem to figure out. If I copy one of the sample themes (e.g. splash) to a different folder (e.g. our-splash), I get strange results. With the aformentioned Splash theme nothing happens at all. The copied version doesn't show up at all. For the formal_white theme, it seems I can disable Moodle entirely by adding a copy of that.
Obviously I need help. Where can I find instructions on how to copy and, then, modify Moodle Themes, the Splash one in particular?
I'd appreciate any help you can offer!
