Python flask app not working

here is the site: http://ift.tt/1cEdyMo

There are several pages, some work, some don't. The root page (/) returns an error. The /welcome page works. The /login page works, but when you click to login it returns an error. The /logout page works. I think that's it.

Here's the github repo for the site: http://ift.tt/1CVDs4h

The error only started occurring after I added the sqlite. I followed the discover flask Youtube tutorial through number 5 and don't know where I went wrong (i don't have enough rep to post the link for that)

Here is the error log:

If someone would be able to do a teamviewer with me for a couple of minutes to see where I went wrong that would really help me out. Thanks!
