Base page fails to recognise Page Templates in subdirectories.
Currently, the CiviCRM base page fails to apply the selected Page Template if that template does not reside in the root directory of the theme. The fallback
page.php template is used instead.
Steps to reproduce
page.php template from the active theme into a subdirectory, rename it and replace its header with:
/** * Template Name: CiviCRM Test */
Then select "CiviCRM Test" as the template for the CiviCRM base page.
The template will not be loaded and
page.php will be used instead.
The code to find the Template "name"
$template_name = basename( $template ); is too simplistic.
PR to follow.
