Flask Issues

[iainstott]

Hi guys, hoping someone fancies helping me out. I have written a central heating control script in python 2, and as I haven't really done much with python 3 yet and I have some new features I want to add, I have decided to re-write the script using python 3 and a bit better planning.

I started some today and thought I would get flask up and running within the script before going on to other parts, I have flask working to a degree using a link I can't post yet. I got it to return hello world in the first part, but then when moving over to templates I get server 500.

Then I always get this when i run the script

Output:
--- Logging error ---
