 Line 1039 of wp-includes/post-template looks like:


 {{{
 if ( in_array( $page->ID, $_current_page->ancestors ) )
 }}}

 ... but in some circumstances, $_current_page->ancestors is null, which
 results in an error being thrown. I suggest testing the variable before
 passing it:

 {{{
 if ( gettype($_current_page->ancestors) === 'array' && in_array(
 $page->ID, $_current_page->ancestors ) )
 }}}
