Made a commit that, unbeknownst to me, was large and now I've exceeded the 1 GB limit. So, my repo is read-only. I have cleaned the history locally and removed the large files. But I can't push those changes.
From the docs it seems this issue requires contacting support........
which you can't do with a free account...which caused the 1 GB limit.
Anyway this post is an attempt to get a fix that doesn't require just making a new repo.
