 When we changed hierarchical False to True for Taxonomy then we received
 Fatal Error.


 {{{
 taxonomy_meta_box_sanitize_cb_checkboxes
 [11:39 AM] Uncaught exception 'TypeError' with message 'array_map():
 Argument #2 ($array) must be of type array, string given' in /var/www/wp-
 admin/includes/post.php:2091
 }}}



 This is happening because of **taxonomy_meta_box_sanitize_cb_checkboxes**
 function. This function not has the checked if the **$term** is array or
 not which is causing fatal error.

 We can use is_array condition for this like already done in
 **taxonomy_meta_box_sanitize_cb_input** function.
