| ======== | |

| 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. | |
