Hi George,
Please use the following code

/**
 * Hide empty MediaPress Gallery from admin galleries list.
 *
 * @param WP_Query $query query object.
 */
function mpp_admin_hide_empty_galleries_from_galleries_page( $query ) {

	if ( ! is_admin() || defined( 'DOING_AJAX' ) || ! $query->is_main_query() ) {
		return;
	}

	if ( $query->get( 'post_type' ) != mpp_get_gallery_post_type() ) {
		return;
	}

	$meta_query = array(
		array(
			'key'     => '_mpp_media_count',
			'value'   => 1,
			'compare' => '>=',
		),
	);

	// side effect: it will override any other meta query for the galleries list.
	$query->set( 'meta_query', $meta_query );
}

add_action( 'pre_get_posts', 'mpp_admin_hide_empty_galleries_from_galleries_page' );

Hope this helps.

Hi Herve,
Sorry, but there is no straightforward way to do it based on the xprofile data(atleast in 2.9.x version).

You can translate to English.

Just make sure to use the proper suffix in the generated mo file(e.g -en_Us.mo or -en_GB.mo etc).

By default, if you haven’t specified a locale, it is set to en_US.

Please give it a try and let me know if that works for you or not?

Thank you
