I just tried installing Solo theme. It was successful. Can you try installing again? Or share more details about your set up, so we can help you troubleshoot.

I suspect that the latest version of Solo assumes the latest version of Ghost, and you’re running something older. How old is your version of Ghost, and can you update it? That’ll probably fix you right up!

Definitely not the latest version, and that’s your problem. :) Comments came in around version 5.8.
