If GPIO is undefined your initial setup may have been incomplete, i.e. the 
compilation of the native C module for GPIO may have failed.

Redo setup and check if everything went through correct.

I have same issue, redo setup multiple times and it does not work.
Raspberry PI 2 is fresh Raspian installed and second thing done is install 
WebIOPi.

I believe it's the GPIO library not compatible with Pi2 yet. Hopefully they 
will release new update soon. Finger cross!

Hi, complete Rpi newby here, but getting the exact same error - all routes seem 
to lead to an incompatibility with the new Pi?

To add, I updated to RPi.GPIO 0.5.10 and still get the same issue. The error 
materializes in the verbose logging when I click any of the buttons / pins on 
the GPIO-Header page.

During handling of the above exception, another exception occurred:

I got same error on Pi2. Please help!

Here is the fix: http://www.techboard-online.de/thread-32-post-76.html#pid76

The unfixed Version of WebIOPi doesn't support the Raspberry Model 2.
