I'd like to have the categories displayed before the title of a post when in a single page.
Like "Parent Category » Child Category » Post Title". When I tried just using the get_category_parents function like:
<span class="title"> <?php echo get_category_parents($cat, TRUE, ' » '); ?><?php the_title(); ?> </span>
it didn't work and I got the error "catchable fatal error: object of class wp_error could not be converted to string in /home/.../single.php on line 7".
Is there anyway to do that? Thanks.
