It wasn't just the main page. SMF, MediaWiki, the download pages, and in general everything in the server (apache, php, mysql, everything)was updated and fine-tuned. There are still some quirks we have to fix, but as for why your problem occurs, to find it I would ahve to debug what SMF does when sending that sql query to the database, and seeing why it returns empty. Right now I'm afraid I have no time to do so.
Later, maybe.
