I am kind of newbie to wordpress, but not to php. I tried network on my site, and ran into the dreaded warning message
“Warning: An existing WordPress network was detected.”
. After spending some time trying to figure out, I ended up peeking into network.php.
To turn on Network, we need to add a constant, WP_ALLOW_MULTISITE. After this, when you try to install Network, it gives you the list of constants to be added to wp-config.php file. When I copied, I missed copying “define( ‘MULTISITE‘, true )” thinking this is already there. Both these constants have to be there in the wp-config.php for network to work.
Once I fixed this, I got the message,
“Notice: The Network feature is already enabled. …”
which is good.
Several sites that suggest fixes for this issue, mix up between these 2 settings as if they are one. Beware.
