Wordpress Categories Box Problem

Hi.

I have a problem with one wordpress theme. I can’t see Categories Box from Add/Edit post. It is visible in custom post types, but in default post, not.

I have no idea what to do.

After 2 hours searching on Google I ask for help here.

Please, help me.

Note: If I activate “twentyeleven” theme all is fine.

OMG .

A stupid mistake. I had this code in functions.php file which I forgot to remove.

function blog_remove_taxonomy_boxes() {
    remove_meta_box('categorydiv', 'post', 'side');
}
add_action( 'admin_menu' , 'blog_remove_taxonomy_boxes' );

Regards.
