What steps will reproduce the problem? 1.install webiopi 2.add two line on /etc/webiopi/config [GPIO] 7 = OUT 1 8 = OUT 1 3.sudo webiopi -d -c /etc/webiopi/config ...
WebIOPi version used? =>0.7.0
Python version used? =>3.2
Distro used? (WebIOPi has only been tested on Raspbian Wheezy) =>Raspbian
Raspberry Pi board revision? (1 or 2) =>2
For Javascript side bugs, Browser? =>no
Please provide any additional information below.

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: https://www.techboard-online.de/thread-32-post-76.html#pid76
The unfixed Version of WebIOPi doesn't support the Raspberry Model 2.
