I am trying to manually upgrade my WP from 3.6.1 to 3.7.1. I've followed the steps... de-activated all plugins, copied all files, etc.
When I go to /wp-admin/upgrade.php in order to upgrade the database, I get this error:
Parse error: syntax error, unexpected T_PRIVATE in <PATH>\wp-admin\includes\screen.php on line 154
The site comes up (thankfully), but I cannot access the admin site (thus, I can't reactivate my security plugins!)
