Slickr confused

I’ve installed the Slickr plugin and it’s working well, with the exception of the page title. It shows as “Page not found” and I can’t find a way to change it or even where the header is generated.(!?)

I’m also confused about the URL structure. I’m new to php, but when I see a URL like http://www.bluemoonkites.com/wp/gallery/ , I’d expect a /gallery/ directory on the server, but no such animal. Sorry if that’s a silly newbie question, but…

Thanks, Ken
