WordPress Network Admin

Hi everyone, I would like to ask what I need to do to disable the network admin for my blogs.

Now I will explain: I had WordPress on a subdomain to try it out and to act as a backup whilst I messed around with the css and php. Now I have disabled that site and taken down the WordPress platform from it – only I still have the network admin running.

I have recently installed a plugin that arranges an xml sitemap for me only it doesn’t work for “multiple sites” – which it assumes by my having a network admin in place. The plugin is called “Google XML Sitemaps” by Arne Brachhold.

How do I either disable the network admin (which is a bit of a pain anyway) – or work around it so that the plugin is happy.

Any help gratefully received. Gemma xx
