[Observium] User Creation Failed?

I have been looking around to see what could be the problem for this. I installed a new copy of observium on ubuntu and have followed the instructions given. When I get to the area to create a user by leveraging ./adduser.php , i get a messages stating the User creation failed. Is there something I am overlooking when i do this or some data i can provide or look at that can pinpoint me in the right/general direction?
