I found the the solution that I mentioned above.
I modified the function thinkup_input_breadcrumb() in 00.theme-setup.php file of /admin/main/options/ folder.
169 line :
the_title(); —-> $output .= get_the_title();
177 line :
echo get_queried_object()->name; ———-> $output .= get_queried_object()->name;
does it correct ?
