PhpWiki is a WikiWikiWeb clone in PHP. A WikiWikiWeb is a site where anyone can edit the pages through an HTML form. Multiple storage backends, dynamic hyperlinking, themeable, scriptable by plugins, full authentication, ACL's.
The installation broke completely, and the password I passed for admin is not working.
Sorry, but I can't get anything but a blank page after install. Documentation is abysmal, support material is ancient and sparse, and your OWN installation appears to be busted in any case. Now I have a failed installation and database to clean up.
Can't recommend this product as even their own installation doesn't appear to be working.
