Activity page does not show commits, comments
I've upgraded from 8.6 to 8.13 through the https://gitlab.com/gitlab-org/gitlab-ce/tree/master/doc/update Everything is fine except Activity page. Activity page only shows who was joined to the project, nothing else. I tried too many advice like re-creating hooks, file/folder permissions, restarting and flushing redis, migrating old repos, etc. about 2 days.
I executed sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
and everything is green:
Checking GitLab Shell ...

Any suggestions will be appreciated.
