Breadcrumb Alias Not Working

titleField
This is used if you wish to change the default page field to be used as the title of the breadcrumb navigation "crumb".

The default value is `pagetitle`

Example:
[[Breadcrumbs? &titleField=`alias`]]

This would make the title of the breadcrumb navigation "crumb" the documents alias rather than the default pagetitle. 

    // $titleField [string]
    // To change default page field to be used as
    // a breadcrumb title, default is pagetitle
    (isset($titleField)) ? $titleField : $titleField = 'pagetitle';

    // $titleField [string]
    // To change default page field to be used as
    // a breadcrumb title, default is pagetitle
    (isset($titleField)) ? $titleField : $titleField = 'alias';

 $docInfo = $modx->getDocument($modx->documentIdentifier,'id,pagetitle,menutitle,published,deleted,parent,hidemenu,description,longtitle,introtext');

// Configuration Settings

// $maxCrumbs [number]
// Max number of elements to have in a path.
// 100 is an arbitrary high number.
// If you make it smaller, like say 2, but you
// you are 5 levels deep, it will appear as:
// Home > ... > Level 4 > Level 5
// It should be noted that "Home" and the current
// page do not count. Each of these are configured
// separately.

// 1 will show all documents in path EXCEPT the unpublished.
// Example path (unpublished in caps)
// home > news > CURRENT > SPORTS > skiiing > article
// $pathThruUnPub = true would give you this:
// home > news > skiiing > article

// Included classes
// .B_crumbBox Span that surrounds all crumb output
// .B_hideCrumb Span surrounding the "..." if there are more crumbs than will be shown

// .B_firstCrumb Span that always surrounds the first crumb, whether it is "home" or not
// .B_lastCrumb Span surrounding last crumb, whether it is the current page or not
