Add the following function to the template.php for your theme:
function yourthemename_preprocess_page(&$vars, $hook) { if (isset($vars['node'])) { // If the node type is "blog" the template suggestion will be "page--blog.tpl.php". $vars['theme_hook_suggestions'][] = 'page__'.$vars['node']->type; } }
Change the "yourthemename" in the function name to match the name of your theme.
