Search function problem in production environment

[Mikko Meronen]

Hi again,

I am trying to deploy a search function to my website. It works well in the development environment, but in the production side I get the error message below (and my codes). I appreciate a lot if someone could help me again. I'm using PythonAnywhere in production, if that matters.

Best regards,

Mikko

The code seems to work in production environment after all, just needed to restart the site.
