 This theme is fairly dependent upon a proper `BaseURL` being set in the `config.toml`. This has to do with how the feed is generated as well as some of the social metadata (these things cannot be relative URL's). I'm fully aware that this can cause issues with some build systems, and I'm trying to work on a good solution for this. This must end in a slash. Example: `https://www.arresteddevops.com/`
