[Flask] No application found.

[SheeppOSU]

If it helps, I get a different error from the website, the error I named above is when i try to query Post from the website debugger. The error I get is -
AttributeError: 'NoneType' object has no attribute 'drivername'
The last lines of code are -

The default implementation provides some saner defaults for things
        like pool sizes for MySQL and sqlite.  Also it injects the setting of
        `SQLALCHEMY_NATIVE_UNICODE`.
        """
        if sa_url.drivername.startswith('mysql'): #This line gives the error
            sa_url.query.setdefault('charset', 'utf8')
            if sa_url.drivername != 'mysql+gaerdbms':
                options.setdefault('pool_size', 10)
                options.setdefault('pool_recycle', 7200)
        elif sa_url.drivername == 'sqlite':

I'm thinking I will just start over
