wp_list_categories showing only first level when logged out

I’m using a custom theme.

When logged out of admin, wp_list_categories is showing only first level of categories, so no subcategories are printed.

When logged in, all categories are shown.

Im usgin the code below:

wp_list_categories(array(
						//'parent' =>  0,
						'hide_empty' => 0,
						'title_li' => '',
						'show_option_none' => '',
						'depth' => 10,
						'exclude' => '1'
					));

Any toughts?
