I forked a Project on GitHub and then opened my fork in GitHub Desktop (Windows 7). Locally, I created a branch and made changes to the code. Now I want to commit the changes, then publish the branch to my fork on GitHub, and then make a pull request to the original repo. That is how it used to work the last time I did this.
But now GitHub Desktop unasked protects this branch ("branch is a protected branch. Want to switch branches?"), and I can not commit things to it. On GitHub, in the settings of my fork, under "Manage Access", it says:
0 collaborators have access to this repository. Only you can contribute to this repository.
But I can not do this (contribute to this repository).
How can I "unprotect" that branch and commit to it?
