Pages for ports 8888 and 8889 are blank

[angelfish0808]

After the new version 7.13 is opened, the pages with ports 8888 and 8889 are blank, and those after 8890 are normal. When testing jupyterlab, there is no such problem.

Having the same issue in two of my conda env where

(env1) student@zbook15:~$ jupyter notebook --version  
7.0.8

(env2) student@zbook15:~$ jupyter notebook --version  
7.1.3

Hi @angelfish0808 thank you for opening this issue. Could you provide the output you get from the terminal where you start Notebook, and the output of the console? Do you see any errors in either?

Does this problem persist after you clear your browser's cache and local storage? It's possible that something is being cached as an application manifest for localhost:8888 and 8889 from a prior version, for example.

@angelfish0808 Any update on this issue after you clear your browser's cache and local storage? Thanks!

@JasonWeill @RRosio @navaneethnpk I didn't clear the cache, but I recently automatically updated other dependency packages, and now I can open them normally.
