Hi @stoo2000 - the documentation for the cookie adjustment for subdomains is very sparse on detail. What do I need to do to configure the cookie setup correctly that this link refers to?
If your WordPress (or IPS4) installation is on a sub-domain, you will need to edit your WordPress configuration to enable it to set Cookies on the root domain. ( http://codex.wordpress.org/Editing_wp-config.php#Set_Cookie_Domain )
Thanks!
