thanks! it works very well now!
I love you!

In w10 I have the same problem but it does not solve only with this. To solve it, I went to the directory"AppData\Local\Programs\Python\Python37\Lib\site-packages\notebook\templates" and edit the file "page.html" on line 18, changing the double quotes with single quotes.
Before:
<script src="{{static_url("components/es6-promise/promise.min.js")}}" type="text/javascript" charset="utf-8"></script>

After:
<script src="{{static_url('components/es6-promise/promise.min.js')}}" type="text/javascript" charset="utf-8"></script>

I had the blank page problem today, and this PR fixed it, thanks. Just had to do CTRL+F5 to force refresh and my Jupyter notebooks are back in business. Thanks!

Thank you sir!

Thank you so much for fixing this, really hope this is merged soon.

Thanks a lot mate !! It solved my MINE issue 👍

How to use this?

Thx^_^
Problem fixed.

How to use this?

You need to locate noteapp.py and override that part.

Thanks for the fix! ❤️

I am still confused about the details of solution

This sounds like it would solve the problem I've had when starting to work with Jupyter, but I'm not sure how to check out this branch (via pip) to confirm this.

I'm trying to use Jupyter with Windows 10 using any of Chrome, Firefox, or Edge. All three browsers exhibit the same behavior - a blank browser window, no apparent errors in the terminal console, but warnings and errors in the browser console relating to MIME type problems. I'm including screenshots here for reference.

Edit: paying close attention toBLGAmazingJ and the diff in this PR, I was able to find the right file and make this change manually. Once this was done, I no longer have the described problem.

Excellent, thank you!

@meeseeksdev backport to 5.7.x

I have tried moving my version of notebook back to 5.7.4 but no luck so far. Can someone comment as to how I can build from source into my conda environment, in order to leverage the fix described in the comments above? Or will this fix be included in an upcoming release that I can utilize viaconda update notebook?

BTW I have tried the following command, but it failed with a compilation error regarding a missing "bower" (which I was not able to find/install, so I gave up):

$ pip install git+git://github.com/jupyter/notebook@5.7.x

Thanks in advance for any assistance with this!

Working on publishing 5.7.7 now.

nodejs and npm are needed to build notebook from source.

Is there a way of fixing the root cause, i.e. that the registry has the wrong mime type?

I'm not a Windows expert, but fromthis, it appears to be inHKEY_CLASSES_ROOT\MIME\Database\Content Type. Ithink the root cause is installation of certain software may modify this database, perhaps as a way of associating itself as an opener for file extensions.

5.7.7 ison pypi

Thanks,@minrk . I found it inHKCR\.js\Content Type (for Windows 10) and changing that also fixed this problem.

Can anyone help how to apply this solution, i.e how to "add in a mimetypes override for .js files"?!
