I created a 24-hour show for Saturday, filled it with music, and then edited the show to have it repeat every Saturday indefinitely. As soon as I clicked 'Ok' the show repeated but all shows were empty!
Perhaps I was not as clear in my report as I would have liked, Albert. I understand that copy/paste content does not work when repeating shows, but it should not have deleted everything from the original show. The fact that my original show is now empty is what I was reporting.
It's pretty easy to repeat, I am having same issue. Create a show, fill it with content - and make it for example weekly repeatable. Select all days and when calender comes back, shows are in place but they are completely empty of content.
I installed Airtime yesterday on an Ubuntu 12.10 32-bit VPS and I've come across the same bug while doing some initial testing. The effect is replicable both on Firefox 18.0.2 and Chrome 23.0.1271.97 m. The initial show's contents disappear if you change its "repeated status", both turning it on and off.
