I use K2 to publish my articles on my website, everything was working fine untill i logged out on the website then i realised all the k2 items had dissapeared from my homepage, everything reappears when i log in. how do i make everything visible for the public? thanks for your help

Check to be sure the access levels on the menu, k2 categories, and items are public

Done it, i had the catagory access level set to special. thanks for your help an the quick response :)
