Description

I recently Updated gitea from 1.0.2 to 1.5 now i noticed, that all of my private repositories are not available (404-Error). But they show up on the list of my repositories and they show up in the administrative view but i get the same error. I tried to re-login, because i thought it might be a problem with the session, but it does not help.
I have a organisation with a private repo, which just works fine,
