Getting 404 Error when trying to access some section in my existing repository

I installed Gitlab on my local server.
I can’t access some of the section of my repo after I restarted the gitlab server.

I get 404 error on the following page.

  • Overview > Detail
  • Repository > Files
  • etc.

But some section works fine

  • Overview > Activity
  • Issues > List
  • etc.

And I can’t push or pull code from the repo.
