I have updated my blog to WordPress v2.9 which was just released. I did the auto upgrade option again which seems to have worked well. Even so, once again I had to edit the /wp-includes/vars.php file to force $is_apache to true (see below) since the SERVER_SOFTWARE variable comes back as WebServerX instead of Apache.
// Server detection /** * Whether the server software is Apache or something else * @global bool $is_apache */ //$is_apache = ((strpos($_SERVER['SERVER_SOFTWARE'], 'Apache') !== false) || (strpos($_SERVER['SERVER_SOFTWARE'], 'LiteSpeed') !== false)) ? true : false; $is_apache = true; /** * Whether the server software is IIS or something else * @global bool $is_IIS */ $is_IIS = (strpos($_SERVER['SERVER_SOFTWARE'], 'Microsoft-IIS') !== false) ? true : false;
I also had to edit the /wp-login.php file and add session_start(); at the beginning for the Register Plus plug-in to work properly as PHP sessions are not automatically started:
session_start(); /** * WordPress User Page
Other than the modifications above, which I have always had to do, the upgrade went smoothly.
Of course, I did perform a complete database and file backup before upgrading!
