The upgrade went smoothly and everything is fine *except* in the Dashboard, where I am supposed to get widgets I get
Fatal error: Unsupported operand types in /path/to/wp-admin/index.php(101) : runtime-created function on line 1
I can't tell if that is a PHP version error (I'm on 4.3.2) or a problem with a plugin (I deactivated all, same problem) or what. Anybody else experience this? I'm seeing other fatal errors on the forum but not this one.
Fortunately everything else is working. Thanks!
