I’m having the same issue. Here is the html the plugin is generating:
<div class="breadcrumb"><a href="/home">Home</a> > <a href="/POST URL/"></a> > <a href="/topics/">Topics</a> > <strong>POST TITLE</strong></div>
So it’s generating a link to the current post, but not including the title. And it shouldn’t be doing this at all.
Other than this odd bug, it’s a great plugin and is helping me a lot.
