Problems installing Elgg

Hi

I am installing Elgg 1.8.3 onto my Centos 5 server running Apache 2.2.22 which I use Kloxo to configure. But when I go through the install steps I get the error message:

We think your server is running the Apache web server.

The rewrite test failed and the most likely cause is that AllowOverride is not set to All for Elgg's directory. This prevents Apache from processing the .htaccess file which contains the rewrite rules.

A less likely cause is Apache is configured with an alias for your Elgg directory and you need to set the RewriteBase in your .htaccess. There are further instructions in the .htaccess file in your Elgg directory.

I have looked on the elgg website and the two suggestions seem to be that I am installing to a different base directory (which I am not) or mod_rewrite is not configured.

I have checked the mod_rewrite and it seems to be configured correctly (I performed the mod_rewrite test in a test sub directory (using rewrite base of /test/) and this works correctly, but the install still says I have the same issue).

I am using an elgg sub-domain but I don't think this should be an issue.

Is there anything else I can check or has anyone else installed it onto a Kloxo managed system?

Thank you for your help
