We have a self-hosted Gitlab instance.
I used BFG-Repo-Cleaner and everything went well, but when I try to push changes I get this:
remote: GitLab: You are not allowed to force push code to a protected branch on this project.
P.S. I'm owner of the project. Earlier I made fork of this project and I had no problems pushing changes there.
I assume you know what you are doing and you really want to force a push. GitLab disallows a forced push to the master branch by default. You can remove that protection. Click the cogwheel icon in your project and select
Protected branches
. Then click theUnprotect
button for the master branch. The forced push will work then.
