Hi Donna
I found a relative simple solution for the next time:
In class-book-review-public.php I changed from line 354
if ( $atts['show_cover'] == 'true' ) {
$html[] = '<span><a href="'. esc_url( get_permalink( $result->post_id ) ) .
'">' . esc_html( $result->title ) . '</a></span>';
if ( !empty( $result->author ) ) {
$html[] = '<br /><span>' . esc_html( $result->author ) . '</span>';
}
}
else {
The result looks nice: buecher-und-videos-illustriert
I’m using unaltered Twentyfourteen.
