Jupyter Notebook not saving: '_xsrf' argument missing from post
The easiest way I found is this:
https://github.com/nteract/hydrogen/issues/922#issuecomment-405456346
Just open another (non-running, existing) notebook on the same kernel, and the issue is magically gone; you can again save the notebooks that were previously showing the _xsrf
error.
If you have already closed the Jupyter home page, you can find a link to it on the terminal from which Jupyter was started.
The solution I came across seems too simple but it worked. Go to the /tree aka Jupyter home page and refresh the browser. Worked.
The only solution worked for me was:
- I opened a new tab in chrome
- I pasted : http://localhost:8888/?token=......
- then I went to my original notebook and I was able to save it
