Empty / stuck GitLab web UI


After I have worked / tried diffrent server configurations have I now got an situation
where I can login on GitLab but nothing else (see attached image).

GitLab “seems” stuck.

I did have GitLab on domain.com:8181 and now have only domain.com
But if thats the problem, when how can I “reset” account and project routes/URLs?

Is there a way to complettly start from the beginning? Reset to first visit so to say?

update: I have tried now to uninstall GitLab completely, removed all traces of GitLab, restart the server and reinstalled. Only to be greated with same blank page after login.

Kind regards,
