an older version of Django:

You have just installed Django over top of an existing

installation, without removing it first. Because of this,
|
|
your install may now include extraneous files from a
|
|
previous version that have since been removed from
|
|
Django. This is known to cause a variety of problems. You
|
|
should manually remove the
|
|
|
|
%(existing_path)s
|
|
|
|
directory and re-install Django.
