@robinruet don't change the status of a support topic that you did not open or are not a person qualified to resolve the issue. Your input here is SPAM, and is not appreciated in the least bit.
@everyone don't download WP Sand Box, it contains several security flaws.
@rsandilands when posting code, please use the code button (back ticks), so that the PHP doesn't get stripped. The proper call for Breadcrumb NavXT is:
<div class="breadcrumbs">
<?php if(function_exists('bcn_display'))
{
bcn_display();
}?>
</div>
I noticed that WordPress ate the PHP parts of this on the Breadcrumb NavXT page on my site, that would have been the correct location to report this, but none-the-less thanks for pointing it out.
