Page title problem

I’m using Elegance theme, and if I enable Ceceppa plugin I cannot get page title.
Now my site just show the url (example: http://home.bdidut.info/contact/)

The theme invoke page title by: add_action( 'mysite_before_page_content', 'mysite_page_title' );
And the function:

function mysite_document_title() {
	global $wp_query;

	# Set up some default variables.
	$doctitle = '';
	$separator = ' |';
	$post = $wp_query->get_queried_object();

…

if ( is_page() ) {

		$page_title_format = mysite_get_setting( 'seo_page_title_format' );
		$page_title_override = trim( get_post_meta( $post->ID, '_seo_title', true ) );
		if( get_post_meta( $post->ID, '_seo_disable', true ) || !in_array( get_post_type( $post->ID ), mysite_seo_posttypecolumns() ) ) {
			$doctitle = mysite_seo_replace( '%page_title%', $post );

		} else if ( !empty( $page_title_override ) ) {
			$doctitle = $page_title_override;

		} else if ( trim( $page_title_format ) ) {
			$doctitle = mysite_seo_replace( $page_title_format, $post );

		} else {
			$doctitle = mysite_seo_replace( '%page_title%', $post );
		}

	}

…

if ( ( ( $page = $wp_query->get( 'paged' ) ) || ( $page = $wp_query->get( 'page' ) ) ) && $page > 1 ) {

		$seo_paged_format = mysite_get_setting( 'seo_paged_format' );
		if( trim( $seo_paged_format ) ) {
			$doctitle = $doctitle . str_replace( '%page%', $page, $seo_paged_format );
		} else {
			$doctitle = sprintf( __( '%1$s Page %2$s', MYSITE_TEXTDOMAIN ), $doctitle . $separator, number_format_i18n( $page ) );
		}

	}

	# Apply the wp_title filters so we're compatible with plugins.
	$doctitle = apply_filters( 'wp_title', $doctitle, '', '' );

	# Print the title to the screen.
	echo apply_atomic( 'document_title', esc_attr( $doctitle ) );
}

Maybe there is problem about using global $wp_query ?
