I’m organization admin/owner for https://github.com/BlockProject3D.
For some reasons now I don’t have access to admin settings for the repositories under Travis.
Here is a link to the Travis page: https://travis-ci.org/github/BlockProject3D.
I just had the exact same issue,
I tried the following and now it’s back to normal:
Thank you that fixed it
I’m having what appears to be the same problem, but clearing cookies didn’t help. Signing out of Github and then signing back in through Travis seems to have fixed it. There is still a little weirdness going on, though. My profile picture isn’t displayed consistently in the top right corner even when I’m logged in.
I have the same issue. Clearing cookies, different order of signing in and signing out doesn’t work. Still no organizations available.
no amount of cookies, private browser, log out login, or any combination worked for me 
Had the same, back in order for me.
I cleared all travis-ci* cookies and it worked again. (This was on Edge (Chromium))
