Issue: Changing Wiki Format Makes Pages Unreachable

When changing the URL format, filename, or spaces characters, most pages in the wiki can become unreachable, especially if the sub-directory routing bug was not fixed before the wiki was installed. The reason is that the URL builder does not first reset the cached wiki index, and subsequent URLs will attempt to build from the existing wiki index URL. Additionally, a root-path needs to be used instead of the base-path for non-zero URL formats, or the non-root directory will duplicate up to the base URL.

Fixed in Alpha 2. Again, it's recommended not to use SEO-formatted URLs if you experience this issue, until Alpha 2 is released or a new build is published.
