升级 WordPress4.0 后 Baidu Sitemap Generator 发布文章时报错！，报错内容如下：Warning: Illegal string offset 'lc_is_update_sitemap_when_post' in ****/wp-content/plugins/baidu-sitemap-generator/baidu_sitemap.php on line 406
Warning: Cannot modify header information - headers already sent by (output started at ****t/plugins/baidu-sitemap-generator/baidu_sitemap.php:406) in /****/wp-admin/post.php on line 233
Warning: Cannot modify header information - headers already sent by (output started at /****l/wp-content/plugins/baidu-sitemap-generator/baidu_sitemap.php:406) in ****/wp-includes/pluggable.php on line 1173
看来是 baidu_sitemap.php 文件里的 406 行代码有问题！
1 、用 notepad++软件，打开 baidu-sitemap.php 文件并找到 第 406 行的以下代码：
if($get_baidu_sitemap_options[' lc_is_update_sitemap_when_post '] == 』1′){
wp_clear_scheduled_hook(『do_baidu_sitemap_by_post』);
wp_clear_scheduled_hook(『do_this_auto_daily』);
wp_schedule_single_event(time()+10, 『do_baidu_sitemap_by_post』);
把这段代码注释掉，注释后的代码如下：
//if($get_baidu_sitemap_options[' lc_is_update_sitemap_when_post '] == 』1′){
wp_clear_scheduled_hook(『do_baidu_sitemap_by_post』);
wp_clear_scheduled_hook(『do_this_auto_daily』);
wp_schedule_single_event(time()+10, 『do_baidu_sitemap_by_post』);
//}
修改 bug 的思路：每当发布文章时，sitemap 都会自动更新。
