also have a look if the theme you are using uses a reset.css (or has some reset css added into style.css) many themes have these and the list styling of bullets etc is removed to make it easier to build nav menus and such
Do you mean the “Menu” link under the appearence tab in wp-admin? Im under the opinion that links not there without this in your themes functions.php add_theme_support( 'menus' ); check if you have that in functions.php if not add it right at the bottom above your closing ?> tag and see if that helps, if it doesnt then remove it..
Yes its real…
it seems it may be having an issue with your multi-site installation, could you give me a list of all plugins (if any) that you have running when installing this one so that i can try to emulate it.. thanks
