However, in the latest Default template, I particularly like being able to include ratings in the recent albums table on the start page. So I kept a copy of the latest Default template, renamed it LatestDefault, and opened it for editing in DaxEdit. The idea was to copy and paste the reference to recent ratings into my favourite theme WITHOUT upgrading to the new build. I included the recent_ratings statement in Declarations in my favourite theme, too.
BUT.... whenever I went to the Start page view in my favourite - edited - theme, I got an "Invalid cover arguments in" template error message. It didn't tell me anything more. I even tried copying and replacing the entire start page, but this generated an HTML parsing error.
