Question

当我尝试在wordpress中保存帖子时，我收到此消息：

致命错误：无法使用WP_Error类型的对象作为数组第354行的wp-admin / includes / post.php

我主题中的第354行：

＆＃13;

if ( ! empty( $_term ) ) {
  $clean_terms[] = intval( $_term[0] ); //Line : 354 
} else {
  // No existing term was found, so pass the string. A new term will be created.
  $clean_terms[] = $term;
}

＆＃13;

这是我主题的 function.php ：

＆＃13;

require_once 'inc/functions-custom-header.php';
