我在wordpress网站上收到警告：
Warning: Cannot modify header information - headers already sent by (output started at /home/content/8305169/html/wordpress/wp-includes/rewrite.php:1) in /home/content/8305169/html/wordpress/wp-includes/pluggable.php on line 1207
我无法访问我的管理面板。我尝试在启动php标签之前删除额外的空间，然后关闭php标签但是没有为我工作。
编辑：
我有两个网站有同样的问题。
我在其他网站上的错误是：
Warning: Cannot modify header information - headers already sent by (output started at /home/content/69/8305169/html/POWER/wp-includes/shortcodes.php:1) in /home/content/69/8305169/html/POWER/wp-includes/pluggable.php on line 1207
请建议我该怎么做。
