I've setup a demonstration setup of Git Stash, attached to a Postgres SQL database. Setup went fine, and I created a new user, a single project, and a single repository in that project.
After pushing my repository to the server, the web interface still thinks the repository is empty:
You have an empty repository
To get started you will need to run these commands in your terminal.
I tried cloning the repository and verified that all the files were successfully pushed and pulled. So, the git part of the server seems to work fine, it's only the web interface that does not think it has files.
git ls-remote origin also verifies that the HEAD is the same both locally and on the server.
Possibly related: The "Audit log" tab under the project level settings and repository settings will never load. The "Pull Requests" tab will also not load.
