GitHub wikis are also git repos, and they are only communicable through HTTPS (pull,push). I, on the other hand, have a global config to use "git://" instead of "https://". That's my preference usually, but clearly that's not the requirement in the wiki case.
Thus, I set the local git config to use "https://" instead of "git://". But this didn't work. I even set the remote URLs again, but they weren't affected at all. Screnshot
I did follow this and this, but to no avail. Any help or suggestion would be appreciated.
