The default home page on my drupal-created website (helixathens.com) seems to have disappeared. I don't think the path changed, so it seems that it was either deleted or renamed by mistake. I went to Site Configuration, then Site Information to edit the Default Front Page. The path was set to "content/home-0" which was giving me a File Not Found error. I tried changing it to "node" which gave the same error, and also tried "home," "home-0," "front," "default," and any other variation I could think of with no luck. I've temporarily set the path to the catalog, but I either want to restore the default front page or create a new one if it really is gone.
The themes appear to be Corolla, Garland, and Minnelli - not sure why there are multiple or if this is correct. I'm taking over the website after its creator has moved on to other employment, and having some trouble figuring out Drupal. I can't even tell you which version we're running (5 or 6 maybe); the interface honestly seems very unintuitive. If someone can direct me towards the best general tutorial, that would be much appreciated, and thanks in advance for any help at all!
