当我试图使用块编辑器编辑或添加帖子/页面时，它会向我显示一些奇怪的警告，然后它们会像消失一样出现，但当我查看页面时，我发现它们仍然存在。警告仅在我使用主题时出现。
Note 1: 大多数警告在wp-admin 或wp-includes 文件夹，我根本没碰过。
Note 2: 我安装了classic editor，它运行得很好。

我创建了一个页面，用户可以在其中检查受支持的帖子格式，问题是如果用户没有检查任何帖子格式，它会返回false，而不是返回包含“standard”的数组，如下所示return [\'standard\'], 我只使用了关键字return 停止函数运行。
Here is what I am talking about:
function get_supported_post_formats(){
$options = get_option(\'post-supports-handler\');
if (empty($options)) {
return [\'standard\'];
}
$formats = [
\'standard\',
\'aside\',
\'gallery\',
\'link\',
\'image\',
\'quote\',
\'video\',
\'status\',
\'audio\',
\'chat\',
];
$output = [];
foreach ($formats as $format) {
$output[] = (@$options[$format] == \'1\' ? $format : \'\');
}
return $output;
}
$output = get_supported_post_formats();
add_theme_support(\'post-formats\', $output);
