I've been running into quite a few problems already and fixing some of the errors myself. However, I've run into something that I have never seen before. I'll explain my setup real quick and then the problem.
I have Collabtive working inside of an Ubuntu 12.04 Server setup with LAMP, which is running on it's own Virtual Machine via VirtualBox. I had to manually fix the install.php file from TYPE=MyISAM to ENGINE=MyISAM for the installer to work properly. Afterwards, I was able to login and view the Collabtive Desktop.
The problem: I cannot add a new Project. I enter the information and when I click "Add", a form notification pops up completely off the browser window saying "Please fill out this field" and doesn't allow me proceed.
