Renaming the page from "home" to "something else" in the CMS Main and Meta-data tabs causes the CMS to redirect you to error on logout (after that, you can't visit www.yoursite.com/admin anymore). Which files do I have to edit (and how?) to be able to rename homepage to something different than "Home"?

Are you wanting to rename the URL or just the title?

Renaming the URL will be problematic as this is currently fairly hard-coded

Just changing the page or nav title is fine, but you just have to keep the URL as /home/

Well, I don't want to change the URL, so I keep "home" in the Meta-data URL field. But changing Page name and Navigation label in the Main tab is enough to make the CMS redirect to error page on log-out (instead of redirecting to log-in page as it should!). After that, www.mysite.com/admin or www.mysite.com/security/login aren't available anymore and the only way of logging in is to log in through the forum and then acess the CMS by going to www.mysite.com/admin. This thing happens only when changing page title of "home" in BlackCandy, all other pages can be renamed without problems.
So, I suppose I have to edit some file which will redirect me to log-in page correctly (where, and how?).
