I finally got around to updating my production server WebApp from 20.1 to 24.0.

I set up an SPLF Encryption Token on each Slave and the Master (made them all identical and used Copy and Paste to make sure there were not typos), but kept getting this error in the Windows Events

Code:

I removed the Encryption Token and made it blank on the slaves and the master and the WebApp started right up.

It looks like a nice feature with very little (if any) documentation. Any idea why it wouldn't work?
