Any ideas on how to rebuild my blog to republish those six years missing?
Do the posts show up under the Posts section in Micro.blog? If so, something must’ve gotten out of sync when publishing your blog. I’ve actually seen this once on my own blog this week, so it might be a new problem that I’m looking into.
Try going to Account → “View logs” and click the “Rebuild” button at the top. That should fix it.
I’m guessing the blog was still rebuilding - it must take longer than I imagined because looking at it a day later, the posts are all there now
