为啥我更文章的时候回出现这样的错误。。。

更文章的时候出现以下错误，百度了没有相关的问题解决办法，是咋回事，现在不知道咋整。
Warning: curl_setopt(): CURLOPT_FOLLOWLOCATION cannot be activated when an open_basedir is set in /webHome/host1848051/www/wp-content/plugins/baidusubmit/inc/sitemap.php on line 521 Warning: Cannot modify header information - headers already sent by (output started at /webHome/host1848051/www/wp-content/plugins/baidusubmit/inc/sitemap.php:521) in /webHome/host1848051/www/wp-includes/pluggable.php on line 1228
似乎是主机出问题了吧？
