Visitors cannot see widget

Have added e-newsletter widget to footer widget area of my site... Strange thing is when a registered member visits site, he can see the newsletter sign up button (but despite me adding 2 groups to choose from, that does not show up)... BUt a visitor landing on page, it shows nothing at all, totally invisible to them...

first i though it had something to do with membership access level settings so i added allowed rule for under PLUGINS for this plugin, but still it wont show for unregistered visitors

Any ideas?
