I just purchased YouTrack a couple of days ago, and I'm trying to get the basic setup completed. However, I'm having a problem creating projects. I did manage to do so once, right after I got it installed, but now it won't let me create any more (and I actually deleted that first one).
Basically, I fill in the Create New Project form and hit Create, and I get this error:Can't use empty null value text
See attached screen shot for details.
What does YouTrack want me to provide? In the image, the Description field is empty, but I get the same result if I fill it in, and it's not required in any case. I've tried doing this with my own user (which has admin abilities) and with the root user, both with the same result. Finally, I've tweaked the values, for example, used a different name or ID. I just can't get it to work.
Oh, and I restarted the YouTrack application service.
Environment: YouTrack 4.1.3 running on Windows Server 2008, installed using the recommended method. I'm using the application from Safari 6.0.2 on Mac OS X 10.7.5.
