未定义索引：页面，未定义变量：theme_name

Question

我无法自定义页面。我正在调试一个Wordpress网站，因为我有问题。

注意：未定义的索引：第72行的D：\ wordpress-4.9.5-0 \ apps \ wordpress \ htdocs \ wp-content \ themes \ page \ functions.php中的页面

注意：未定义的变量：第72行的D：\ wordpress-4.9.5-0 \ apps \ wordpress \ htdocs \ wp-content \ themes \ page \ functions.php中的theme_name

问题出在哪里？我能做什么？
