[Flask] Finding error in Flask app while running under web server

[Alex Hall]

Thanks, good to know I'm not missing another automatic log file somewhere.

I also discovered that you can set catch-exceptions in UWSGI to true, and
that will cause any problems to be printed. That may not help Flask
directly, but it explains why my UWSGI log was always empty, as it showed a
permissions problem with the file. If I printed with Flask, I wouldn't have
seen anything, and I would never have known why were it not for
catch-exceptions.
