I installed wordpress and got things out of order -- plugins before creating network. So I started over.
I installed wordpress again with a new database. I created a network, using network.php and making the changes it said to wp-config.php and .htaccess.
Now going to testing.mysite.com/wp-admi
I get "You do not have sufficient permissions to access this page."
Most places say to deactivate all the plugins first. But on this new installation, no plugins were active. I'm following the simple steps verbatim. What am I failing to understand?
P.s. it's Wordpress 4.1.1. I've tried the hack of the theme's functions.php to make me a superadmin:
include(ABSPATH . 'wp-admin/includes/ms.php');
$user = get_userdatabylogin('YOUR_USERNAME');
all to no avail
