This is the reply i just got.

Thank you for your reply. I apologize for any confusion, however, this is not an issue with your DNS settings. I have thoroughly checked the DNS settings of your domain name and they are set properly. It ap;ears you have a redirect set up that causes the www version of your domain to automatically redirect to youronlinecenter.com without www applied. I apologize for the confusion once again, however, this is not a DNS issue nor a server issue. This is definitely an issue with a redirect set on the website, possibly in your .htaccess file as previously stated.

Please note that we are unable to support third party application issues and we do not support the inner functionality of this program. If you are having difficulty using a third party product, we can help troubleshoot that process to the point that we find that the issue lies entirely within the configuration of that product. If you believe the issue is caused by something within our system please reply with as much pertinent information as possible and we will further review the issue.

Please let us know if we can help you in any other way.

I also believe its something with the htaccess file as other websites on the server prior to Multi user websites are working perfectly with the www. and none www.

This is currently my htaccess file

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
# END WordPress

The sites are mapped to separate domains at a later stage and before being mapped they are subfolders

no i just have the standard set up from when you install multi-site.
