statistics.html.tmpl file is not generated
lucien mornet
Hello,
I think I know why the statistics.html.tmpl file isn't being generated.
In the logs, I have this:

I have three years without data: 2014, 2015, and 2020. The station is down.
How can I solve the problem?
I read this: https://careerkarma.com/blog/python-valueerror-max-arg-is-an-empty-sequence/
Thank you for your answers.
I am in France and do not speak English. I translate with Google.
