I get a fatal error message when I try to automatically upgrade from 2.7 to 2.7.1. Is anybody else having this problem? The message I get is: Fatal error: Cannot redeclare class pclzip in /home/content/D/e/b/DebbiSmith/html/comeonsense/wp-admin/includes/class-pclzip.php on line 171. I run five sites and have the same problem with upgrades on each. I also have seen the same problem with the latest version of the DashBar plugin.
