I was on my warlock and everything was peachy untill I got DC'd by blizzard from the recent DDoS.

Addon settings and menu commands seem to work but it doesn't actually display the name plates.

Are you sure nameplates are enabled in the blizzard interface options? Because I've never heard of an addon suddenly not working after getting DC'd.

I was just DC'd again, I was able to use the shift click on the reset configuration and that did the trick

I'll let you know if it breaks again when I re-log

Hmm, not reproducible, it worked fine after the DC
