If you’ve indeed tried everything, I don’t think there’s anything more anyone can suggest. It covers the most basic step, that is re-issuing an access token to delete the entire website and reconnect it to GitHub. One of that has to work as said by everyone there.
Would you be willing to retry all of them one by one?
I used Stackbit to create my site. Its a Gatsby site using GIT as CMS. The Netlify CMS configuration is well in place. It is working very well for all my Non-Stackbit sites. But it is not working to any of my Stackbit sites. It gives the following error while logging to Netlify CMS.
Git Gateway Error: Please ask your site administrator to reissue the Git Gateway token
I have regenerated the GitHub API access token many times. I have removed the user and added again but the above error continues. Can anybody help on this?? Thanks.
