title: Flask Server running wrong program
body: <p>I am learning Flask.  </p>
  
  <p>I was able to run the Hello World tutorial as shown here </p>
  
  <p>Then I tried to build the Flaskr program following the tutorial <a href="http://flask.pocoo.org/docs/tutorial/introduction/" rel="nofollow">http://flask.pocoo.org/docs/tutorial/introduction/</a></p>
  
  <p>I ran into an issue with the Flaskr program accessing the database,specifically "sqlite3.OperationalError
  OperationalError: unable to open database file"</p>
  
  <p>so I took a break and went back to seeing if I could run my "Hello World" program.</p>
  
  <p>Now when I go to the url 127.0.0.1:5000/, instead of seeing "hello world" I still see my data base error from the Flaskr program.</p>
  
  <p>It seem like I need to reset the server instance or something?  Please help!</p>
