Having Issue no Multinetwork site

Hello,

If you give me some more information:
– which version of wordpress
– which version of very basic content restriction
– which kind of webserver
– symptoms of “not working” exactly (restriction does not work, blank page)
then I might help you out.

Otherwise, please verify:
– are you connected to wordpress’ admin of your site?
In that case it is normal that the restriction does not apply. It works only for non connected users.
