CDSEO users, use this alternative breadcrumbs code in
/skin/reboot/customer/bread_crumbs_desktop.tpl
Code:
<ol class="breadcrumb p-0 border-0 rounded-0 d-none d-lg-block" itemscope itemtype="https://schema.org/BreadcrumbList">
{foreach from=$location item=l name=location}
<li class="breadcrumb-item text-{$config.Reboot.reboot_breadcrumb_text_colour|default:'dark'}" itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem"><a itemprop="item" href="{if $smarty.foreach.location.first}{$current_location}{else}{if !$smarty.foreach.location.last}{$l.1|amp}{else}//{$smarty.server.HTTP_HOST}{$smarty.server.REQUEST_URI}{/if}{/if}"><span itemprop="name">{if $smarty.foreach.location.first}<i class="fa fa-home fa-fw" aria-hidden="true"></i>{$config.Company.company_name|amp}{*{$lng.lbl_site_path}*}{else}{$l.0|amp}{/if}</span></a><meta itemprop="position" content="{$smarty.foreach.location.iteration}" /></li>
{/foreach}
</ol>
Then comment out, or delete the breadcrumbs JSON-LD code section in
/skin/reboot/custom/json_ld.tpl
