One element that seems to catch a lot of people out is the featured content space (the images at the top of the homepage). These are controlled with tags. You select a tag in the theme customiser and then add the tag to the posts you want displayed in the featured content area. There’s more info on the Bromley support page.
Use this forum to ask me questions about the theme or report any issues you’re having. I’ll do my best to resolve them as soon as possible!
