go to wp-includes/template.php
Insert this chunk of code
// in wp-includes/post-template.php
/**
* Get the specific template name for a page.
*
* @since 3.4.0
*
* @param int $id The page ID to check. Defaults to the current post, when used in the loop.
* @return string|bool Page template filename. Returns an empty string when the default page template
* is in use. Returns false if the post is not a page.
*/
function get_page_template_slug( $post_id = null ) {
$post = get_post( $post_id );
if ( 'page' != $post->post_type )
return false;
$template = get_post_meta( $post->ID, '_wp_page_template', true );
if ( ! $template || 'default' == $template )
return '';
return $template;
}
After this chunk of code
function get_page_template() {
$id = get_queried_object_id();
$template = get_page_template_slug();
$pagename = get_query_var('pagename');
if ( ! $pagename && $id ) {
// If a static page is set as the front page, $pagename will not be set. Retrieve it from the queried object
$post = get_queried_object();
$pagename = $post->post_name;
}
$templates = array();
if ( $template && 0 === validate_file( $template ) )
$templates[] = $template;
if ( $pagename )
$templates[] = "page-$pagename.php";
if ( $id )
$templates[] = "page-$id.php";
$templates[] = 'page.php';
return get_query_template( 'page', $templates );
}
That’s what worked for me. Good luck!
