In the documentation for upgrading to 4.02 I find the following instructions:
1) Check for new config-inc.php variables, some recent additions are:
$cookie_domain has been added for website cookies. I highly recommend setting this to ".youdomain.com" where yourdomain is the name of your domain. This will enable cookies to be read across your website regardless of the URL (i.e. galley.website.com and forums.website.com). If you are using a forum integration you must have this set in both your forums and photopost.
However in the config-inc.php file in my 4.02 download there is no $cookie_domain section in the file.
I'm I missing something, or are the upgrade instructions incorrect?
