I raised a question about this already but it seems to have been lost in your system.
I have installed this plugin and network enabled it. I then enabled Login Image, Global footer content, dashboard footer content, Rebranded meta widget, Site Generator replacement, Network wide text change, Custom admin CSS and Custom login CSS.
I then go to one of my sites using another browser and it displays it is a Wordpress site with <div id="site-generator"><a target="_blank" href="http://wordpress.org/"
Please tell me what I am doing wrong.
