So you can, here it is properly as I can't edit my post any longer.

If by this you mean going to mydomain.com/grafana, then yes, I get a 404 error. If you mean I should try something via SSH, then I can give it a go? I'm quite happy to wipe it though and start afresh, I just want to try a last-ditch effort to extract my data, if it is still there.
