Just installed the 0.7.0 version of Simple PHP Blog to my server, and noticed, that the internal links and redirects did not work. This was because the BASEURL was missing a "/" at the beginning. Am using Lighttpd on the server, so this issue might be caused by it (previously used sphpblog with apache with no issues). Anyway, thought I'd send you a patch that adds a slash to the beginning if it is missing. Hope this is helpful.
