Expert Pages Wont Display - Error with Breadcrumbs?

The Jobs & Experts plugin wont display the pages it creates for experts (I haven't tried jobs yet). You can see the error here:

The error it is showing is:

Catchable fatal error: Object of class WP_Error could not be converted to string in /home/o743r5b0j0/public_html/wp-content/themes/solana/includes/breadcrumbs.php on line 45

How do I fix this?
