Re: I\'ve got different themes on different pages
There are a few older posts talking about the dangers of using one-click install scripts to install WPMU and/or BuddyPress. IMO, if you are going to create a community site, you should take the time to carefully set it up. Toward that end, I place manually installing WPMU and BP as an important first step. You have more control over the process and gain a much better understanding of how your site is configured.
I’m glad that you’re up and running now after a clean, manual reinstall.
