search reveals directory structure??

Err….hang on….forgot to search the forums….geeze…clueless me.

Ok, if I switch to the Twentythirteen theme, the problem goes away. Question is, why?

I tried deactivating all the plugins, which didn’t have any affect on the search.

One site suggested supressing php notifications. Not really convinced that is the best way.

A response on this thread seemed to have worked for me:

***
I read several posts about putting (array) in front of the variable and while I am clueless about how or why it works, it stopped the darn error messages on my web site! Yay!

/**
 * Builds URI for a page.
 *
 * Sub pages will be in the "directory" under the parent page post name.
 *
 * @since 1.5.0
 *
 * @param mixed $page Page object or page ID.
 * @return string Page URI.
 */
function get_page_uri($page) {
	if ( ! is_object($page) )
		$page = get_post( $page );
	$uri = $page->post_name;
/* Added (array) in the offending line below */
	foreach ( (array)$page->ancestors as $parent ) {
		$uri = get_post( $parent )->post_name . "/" . $uri;
	}

	return $uri;
}
