I just started seeing the error on startup:
 Collisions detected in jupyter_notebook_config.py and jupyter_notebook_config.json config files. jupyter_notebook_config.json has higher priority: {
     
"NotebookApp": {
       
"nbserver_extensions": "{'jlsaticserve': True} ignored, using {'jlsaticserve': True, 'jupyter_nbextensions_configurator': True}"
     
}
   
}

Should I be worried about this?  How should I resolve it?

HI Gideon

You do not have to worry, it just means that some config in jupyter_notebook_config.py are ignored.
You likely have:
c.NotebookApp.nbserver_extension = {'jlsaticserve': True}
You can likely remove this line as jlsaticserve is also set to True in the Json config file.

The reason is that config file can be both .py or .json. Json allows packages to automatically update config. Though, conflicts may happen in which case the Json file takes precedence.
Does that make sens ?
