My additions (Gentoo Linux amd64, Jupyter Server 2.9.1, Firefox v120.0, Opera v105.0.4970.13 - updated yesterday)

1. Firefox today started showing blank page and there is error in debug console (F12) : "... TypeError: g[e] is undefined .."
2. while Opera shows the page without problems
3. nbclassic version still shows ok in both

then

4) I don't remember why but ran "jupyter notebook --generate-config" but it did not help; forced update Ctrl+Shift+R too.
5) two hours later, I did not anything else but simply restarted jupyter (not classic) and now Firefox shows the jupyter home page just fine.
Not sure which point has helped but you could try another browser too

EDIT: no, it still does not work, that was running nbclassic.

Regards!

Hi @dankarthik25 thank you for opening this issue! Does this issue happen for you in other browsers as well? The line you provided from the terminal does not indicate an issue, my working JupyterLab instance has a similar output. Is there additional terminal output that you could provide?

[pkartsev]

Hi again!
Today I found the idea about clearing cache and cookies.
Entered Firefox settings and removed 5 cookies belonging to localhost.
Now everything works! on two different PCs.

[RRosio]

Thank you for your reply @pkartsev! Maybe @dankarthik25 could give that a try as well and confirm that this solved the issue for them, then we can close this issue. I will leave it open for now!

[RRosio]

Hi @dankarthik25, just wanted to follow up with you about this issue, are you still experiencing this issue?

cleaning the browser cache helped!

I have the same issue, using notebook 7.1.0. Using Brave and clearing cache didn't help, the start page of jupyter won't load. In Firefox it seems to work fine.

The update notebook may incur the incompatibility issue. Please execute the following commands and then it will work fine.

0. Uninstall jupyter

$ conda uninstall jupyter
or
$ pip uninstall jupyter

2. install jupyter with standard conda command

$ conda install -c anaconda jupyter

3. update jupyter

$ conda update jupyter

4. solve the compatibility

$ pip install --upgrade 'nbconvert>=7' 'mistune>=2'

Notes:

During opening an ipynb file, readers may see the following alert:

Read the migration plan to Notebook 7 to learn about the new features and the actions to take if you are using extensions - Please note that updating to Notebook 7 might break some of your extensions.

Another issue is that users need to take different approaches for different Nvidia drivers (and environments). With regard to v530, the older version of Jupyter Notebook such as v6.x might be better. Wight regard to newer ones such as v535 or higher, the update version of Jupyter Notebook 7.x might be better.

Cheers,

Hi I also have this issue on microsoft edge browser. Jupyter CAD doesn't show up on web page, algo on jupyter desktop.
Only by copying and paste the http://127.0.0.1:8888/cad?token=473b5c664fe3e8b05e8357781f4f26cfc2b9c1ab039d00c6 appeared on the terminal but it is not practical
