Hi all,

I get the following error when I try and install a WIKI on a new site.

---Report---

MediaWiki 1.4rc1 installation * PHP 4.3.10: ok * PHP server API is apache; ok, using pretty URLs (index.php/Page_Title) * Have XML / Latin1-UTF-8 conversion support. * PHP is configured with no memory_limit. * Have zlib support; enabling output compression. * Turck MMCache not installed, can't use object caching functions * Couldn't find GD library or ImageMagick; image thumbnailing disabled. * Installation directory: /a/[snip]/home/[snip]/public_html/wiki * Script URI path: /wiki * Warning: $wgProxyKey is insecure

Fatal error: Cannot redeclare class namespace in /a/[snip]/home/[snip]/public_html/wiki/includes/Namespace.php on line 52

---Report---

I have previously *tried* to install a wiki. Older versions throw back even more errors (but all of roughly the same form). Newer versions merely throw back the namespace class error.

Is there a particular reason for this? If there is not one specific reason,can anyone suggest how I go about finding out where the problem lies? I'm on a fairly steep learning curve here, and clear help would be brilliant.

Cheers Al

p.s. the [snips] are me being aware that I don't know enough about security yet :)
