I' going through the "Introduction to GitHub" course and am stuck on step 2 - Turn on GitHub Pages. I enabled pages and select a theme. But no matter which theme, I'll always get an "Unable to commit _config.yml to protected branch." error message at at the top and cannot progress. This is in the "github-slideshow" project that was created for the course.
How can I progress here?
Were you able to get this to work in the meantime? If not, could you post a screenshot over here?
