Very little except the Adafruit software works with both and throws an error if it can find either!

Since update can't access WebIOpi via http

Webiopi seems broken after RPI update/upgrade!

I can't access a web interface that controls some relays that was set up on port 8080 with WebIOPi. The port has been closed since the rpi update yesterday! PLUS all the relays come on at boot! Even though only one was set to high at boot!
Help!
