Issue with upgrading system image : "unavailable modifier requested: 0"

Dear PythonAnywhere Community,

I have tried to upgrade the system image of my bottle application from "classic" to the "haggis" one.

When I restart my app, I am facing this error : "-- unavailable modifier requested: 0 --"

and this warning message on server log :

  • 2022-10-02 14:01:08 !!!!!!!!!!!!!! WARNING !!!!!!!!!!!!!!
  • 2022-10-02 14:01:08 no request plugin is loaded, you will not be able to manage requests.

  • 2022-10-02 14:01:08 !!!!!!!!!!! END OF WARNING !!!!!!!!!!

Any help would be great !

Thanks

You appear to be back on classic and using Python 3.4, so we cannot investigate what you did when you were on haggis.

Hi Glenn, i have switched to haggis right now

Your web app is still configured to use Python 3.4. That is the problem.

I'm so bad ... Thanks, that's working now !

Glad to hear that you made it work!
