Thanks Chris. That’s working fine now! 😛

Dear Chris,

Actrually, those plugins already add meta box at post and page entry.

function expirationdate_meta_post() {
	add_meta_box('expirationdatediv', __('Post Expirator'), 'expirationdate_meta_box', 'post', 'advanced', 'high');
}
add_action ('dbx_post_advanced','expirationdate_meta_post');

/**
 * Add's hooks to get the meta box added to page
 */
function expirationdate_meta_page() {
	add_meta_box('expirationdatediv', __('Post Expirator'), 'expirationdate_meta_box', 'page', 'advanced', 'high');
}
add_action ('edit_page_form','expirationdate_meta_page');

However in your Live Blogging New Entry not appears.

Any ideas?

Thanks
