Not sure if this is the issue but when looking at the source code I’m seeing an extra ‘>’. This is present on two sites I checked. Here’s the code.
<div class="dp_breadcrumb_main" xmlns:v="http://rdf.data-vocabulary.org/#">You are here: <span class="dp_breadcrumb_span_home" typeof="v:Breadcrumb"><a class="dp_breadcrumb_a_home" rel="v:url" property="v:title" href="http://www.xxxx.com">Home</a></span> > <span class="dp_breadcrumb_span_1 dp_breadcrumb_span_last" typeof="v:Breadcrumb"><a class="dp_breadcrumb_a_1 dp_breadcrumb_a_last" rel="v:url" property="v:title" href="http://www.xxxx.com/laminate-flooring/" title="Laminate Flooring" >Laminate Flooring</a></span></div>
So I’m just adding my two cents here but, I can’t tell the difference, and I’m still getting the error, so fingers crossed I’m hoping that they need to update the Testing Tool
