addon version:
Bagnon-8.2.25-8.2.5

Describe the bug
even after updating it, the addon still doesn't work

Bagnon 1.txt
Bagnon 2.txt

Try to disable bagnon plugins, if you have installed any.
For me "Bagnon ItemLevel" caused bagnon not working at all.

I delete the plugin directory and reinstalled it, that fixed it for me.
