Hi @mattrb and welcome!
The way git-gateway
works is by creating an access token to the GitHub repo. It looks like the generated token doesn’t have write permissions.
Things you can try:
- Disabling/Enabling
git-gateway
from Netlify site settings. - Clearing browser cache (makes sure the CMS connects to the correct instance of
git-gateway
). - Re-linking your site to the GitHub repo (and then disable/enable
git-gateway
) from Netlify site settings. - Creating your own token on GitHub manually and supply it to
git-gateway
via Netlify site settings.
