Why Does Terminal Only Shows Blank Screen

Hi, I’ve been trying to access the console but everytime i’m just met with a blank screen.

Below is what my browser console gives me.

So that works ok for me, is this problem still occurring for you? If so let me know your browser version and OS and we can take a closer look.

I’m going to edit your post to remove your auth token from view.

Yes it is still happening. Google Chrome Version 60.0.3112.101 (Official Build) (64-bit), Windows 10.

Also, I just tried with Microsoft Edge and it worked. It doesn’t work in Google Chrome’s incognito mode so I don’t think it’s a plugin in my browser.

I am having this exact same problem using Chrome and macOS Yosemite.

Any solution, or do I need to use a different browser?

Does it work in an incognito window for you?

well, that’s interesting.

it works in incognito mode. is that a feature or a bug?

also typing refresh at the command line doesn’t update my editor to show me the additional files i see in the console page.

It suggests that’s it’s a plug-in causing your problem.

There are a few reasons why your files might still not show in the editor, even after refresh: https://glitch.com/faq#hidden-files

You rock.

It was a plug-in: https://mybrowseraddon.com/dark-mode.html

I don’t have it turned on for incognito mode.

Is there a list of browser plug-in issues in the FAQs or elsewhere on the site?

No, not at the moment - I will compile one!
