[Flask] Serving a file to downalod AND print message on screen

[sidwoodstock .]

Just some thoughts:

- Verify file is truly placed in /uploads/
- Verify your file server is exposing your uploads directory.
- You can move around the code in your template which shows flashed
messages, perhaps move it to a place which gets called when you want.

To truly help with the uploads / file not found issue, it'd be helpful to
know what other packages you're using.
