I had created a private repo on bitbucket and been pushing my changes to it, but I decided to delete it.
Now, every time I make a commit, I am prompted to push, of course...
How do I change/fix this in SourceTree, so that I don't get the prompt and push icon (upward arrow) in my local SourceTree app?
I just tested a remote origin deletion with SourceTree 3.4.5:
You can remove the remote origin, then recreate it: your master branch will then push to the right one.
