I was wondering, why i could choose ('Display Google Plus Author Profile from Users Profile') but there was no Input field in the Profile to set up the GPlus link.
Not sure if it's a bug or if i missed sth.
I did a dirty hack to fix it. Would be glad if you answer me.
I fixed it by changing the class-admin.php (Inserted between 346 and 347:
<tr> <th><?php _e( "Google Plus Profile", 'wordpress-seo' ); ?></th> <td><input class="regular-text" type="text" name="googleplus" value="<?php echo esc_attr( get_the_author_meta( 'googleplus', $user->ID ) ); ?>"/></td> </tr>
And adding on line 293:
update_user_meta( $user_id, 'googleplus', ( isset( $_POST['googleplus'] ) ? esc_html( $_POST['googleplus'] ) : '' ) );
