Thanks. I gave that a try and the url is now pandorarp.com/wiki_index. Unfortunately, I'm still getting a redirect error.
I changed the wiki url preferences to pandorarp.com/index.php?wiki_index and that seems to work, except it tells me I don't have permission to view the wiki.
Looks like permissions and wiki areas and anything configurable in the wiki CP doesn't save either due to, I assume, url rewrite issues.
I'm just gonna move my forum up to the root directory and remove the need for the url rewriting. Should I uninstall and reinstall the wiki when I do that?
