ejabberd fails to load after apt-get update

Hello,

Yesterday an automated apt-get upgraded ejabberd from 2.1.11-1ubuntu2 to 2.1.11-1ubuntu2.1 (running on Ubuntu server 14.04)

Now, ejabberd fails to start. Trying to start it manually produces the following message:

Does anybody have any suggestions as to how to fix this, or what may be causing it? I assume it has something to do w/ mnesia, but that package hasn't been modified since installation, approx 3 weeks ago. Up until I upgraded ejabberd it was working smoothly. Any ideas?
