New to TestLink and not seeing any buttons!

[Bewdley Bloke]

Hello
I am new to TestLink and a colleague has got it up and runnning on a VM for me. (Version 1.9)
However, as Admin, although I can create Users and assign Roles, I don't seem to be able to create anything else as there a no buttons showing.
For example, if I click on Test Specification all I see is the "Help" text. The buttons such as "New child Test Suite", "Edit", "Delete Test Suite", etc (as per the User Manual) are not visible and, try as I may, I just don't seem to get these up there. The same is true when I go into Requirement Specification.
As a result, I have nothing showing in the Tree (bottom left pane).

I would be really grateful if someone could help me out here.
Thanks and regards
