Unable to visit websites after deleting SelfControl app
You shouldn't have done that… it won't end well :\

From the Self Control FAQ


  Q: How do I disable SelfControl once it has started?
  
  You can't. That's the idea. Just wait.
  
  "But, but but..." you say.
  
  Seriously, chill out. It's not the end of the world.
  
  The timer will run out and the internet will come back again. In the
  meantime, you may find comfort in curling up in a ball under your desk
  and rocking back and forth for a while.
  
  Q: I deleted the application, will that do anything?
  
  No. (Except maybe cause problems with the block disappearing at the
  proper time. Don't do it!)
  
  Q: I did some stuff with the terminal that I read on a cool tech site, but it didn't work, what do I do now?
  
  We don't know what you did or why you would follow instructions found
  on the internet before reading this FAQ. Lesson learned right? Good
  luck!


I would imagine your solution will be to reinstall it &amp; hope the timer runs out correctly.
