我有一个空白主题，纯粹是为了重定向到我的自定义前端。我创建了一个functions.php 并将add_theme_support() 在里面，没有用。

指数php：

<meta content="0; URL=\'https://headless-cms.test\'\'" http-equiv"refresh">

<!-- just in case the meta tag is not read properly, here is plan B: a JS redirect -->
<script type="text/javascript">
  window.location = \'https://headless-cms.test\';
</script>

功能。php

add_action( \'after_setup_theme\', \'headless_theme_setup\' );
function headless_theme_setup() {
    add_theme_support( \'post-thumbnails\');
}

// Also tried these and still didn\'t show

//add_theme_support(\'post-thumbnails\', array(
//    \'post\',
//    \'page\',
//));
//add_theme_support( \'post-thumbnails\' );

我刷新了管理面板并在下面进行了检查screen options 没有看到它。我正在使用WP 5.0.2。
