That's strange. Have you also removed Nerdpack recently?
I'm no expert, but if you're able to access the command line via SSH, you could try to initiate a graceful shutdown ("/sbin/powerdown"), then boot into safe mode, remove the plugin, and reset network settings as described in the linked topic in my first post. I've asked a clarifying question over there given what Tom90 is saying about already having removed the plugin.
