Cannot Delete Git/GitHub Repository

Question

I am totally new to version control of any kind, including: Git and Github. But yesterday I thought I would give it a try for some lecture slides I was working on. You can see my botched attempts at: https://github.com/meaneych

I hastily created a number of repositories. But now I don't want them and would to delete them from Git/Github (I kind of want to undo everything and just start from scratch).

I followed the instruction for deleting repositories at: https://help.github.com/articles/deleting-a-repository However, when I go to click on the "Delete this repository" button nothing happens (ie I don't get prompted with the pop up that should occur at step 4). Why? Have I locked some files, is there some kind of a file access issue, or have I committed some kind of an illegal move that will not allow me to fully delete a repository?

I also tried to follow the command line instructions given here: How do I delete a local repository in git? However, the repositories still remain in Git/Github (I still see them). And also, when in the Mac Github GUI I can't access the Menu - Edit - Delete button to try to delete any local or Guthub repositories as shown here:

I am totally new to Git/Github and just want to start from scratch. How would I delete all these local and Github repositories I made in error? Thanks in advance for your help.

Answer 1

Do you use NoScript or similar addons? It blocks the delete popup for me, if it's activated on the site. If so, try whitelisting github.com.

Edit: unfortunately, I don't have easy access to Safari, so I can't provide help specific to that browser.
