我刚刚更新了我的 Customizr 子主题，我的仪表板上出现以下错误：
警告：在第 653 行的 /home/beaufort/public_html/wp-content/themes/customizr/inc/class-fire-utils.php 中为 foreach() 提供的参数无效
这是第 653 行的内容：
foreach ( $_font_groups as $_group_slug => $_font_list ) {
这就是以下内容：
if ( 'list' == $_what ) {
$_to_return[$_group_slug] = array();
$_to_return[$_group_slug]['list'] = array();
$_to_return[$_group_slug]['name'] = $_font_list['name'];
}
我对php一无所知，所以您的帮助将不胜感激！
非常感谢
