Why Zend Studio doesn't recoqnize my zend server?

If I try to debug, what I see is this screenshot.

enter image description here

Basically Zend says that there is no PhP server selected for test project.

And then the auto generated URL which cannot be chang esays http:///

But I GOT a server. And usually this get taken care off automatically.

What should I have done? How do I specify that the http:/// should have been http://localhost/

Solution

I had the same problem.
My solution:

Go to: Preferences > PHP > Servers
1) Delete all the previous servers.
2) Create a new server (maybe similar to the previous... but new).
3) Edit the new server to select the debugger (because in the "creation window" I can't configure it).

Preferences > PHP > Servers

Preferences > PHP > Servers > Edit

Go to: Preferences > PHP > Debug
Select the new server

Preferences > PHP > Debug

Now it works! (at least in my case).

Now it works!
