Sorry to hear about the issues. We don't really support anything other than the default (underground) theme and mobile theme so I'm not really sure how the White theme got broken. Forum search is something we'd have to disable because the forum is so big now that frequent searching will cause considerable performance problems. It's not ideal, I know. At some point in the future we'll hopefully start to migrate our discussions off the forum and onto a new platform where searching will be easier. The IPBoard forum is a great tool and serves as a backbone to many parts of the website, however, as we didn't write the software we keep coming up against limitations which we have very little power to control. Search is unfortunately one of these cases.
