I'm starting to think that there might be quite a lot of things not working properly with this plug-in. Maybe it's incompatible with the current version of WP and needs an update?
The upcoming dj sidebar widget is displaying the wrong day in the schedule info.
I have a show scheduled on Sunday from 22:00-24:00 and then right after another show is scheduled for Monday 00:00-02:00, but the widget is showing the schedule info for the latter one as Tuesday 00:00-02:00.
The master schedule is showing the correct time schedule though.
