Repositories missing after login

Hi All,

We are running a private GitLab, once we log in and navigate to a project, we get the following error:

The repository for this project does not exist.
This means you can not push code until you create an empty repository or import existing one.

If we select a project, everything seems to be there except for the “Details” under the Project overview heading.

I am new to Gitlab. Please can someone help me with this?
