I installed IJulia and launched notebook(). That worked and version 7.5.1 of Jupyter works as expected, EXCEPT that I cannot save files from the file-> save and export Notebook as. The following error message appears

The notebook is “trusted” and I disabled Firefox extensions.
Same problem when I switch to Jupyterlab in the browser.
Any idea what kind of test I could do to solve the problem ?

What directory (folder) are you attempting to save the notebook to, and do you have write permission there? Running pwd() in the notebook will tell you where you’re trying to write.

Try notebook(dir="somepath") where “somepath” specifies a folder you know you can write to.

Good suggestion. pwd() points to a directory where I can write (a subdirectory of my user directory) and I’m also using Administrator rights for the moment and I succeeded to write files with println. So probably something else is causing the problem.
