I am unable to get themes working (1.2 to 1.5 upgrade) and am really confused about the whole thing. If I have my blog in a subdirectory of my domain, how does it know what theme to use? I've switched themes and it says one is active but it's still my same old design. I have my index file at the root of my domain and I'm thinking that's where the complication is. I've been through all the documentation on upgrading to 1.5 and followed all the steps to use themes. Any ideas?
