Failed to start Docker Application Container Engine, need help

My docker engine won’t start anymore. I have been messing with my Debian LXC container and followed instructions here, but I reverted it and now I cannot get my Docker engine to start anymore. Hopefully someone has an idea how to fix this. I’ve restarted the LXC a few times.
