无法在WordPress中创建新帖子

问题描述：

Suddently the \"publish\" button has vanished, and there is the \"send for review\" button instead on new posts.
When clicking the \"save draft\" button I get \"you are not allowed to...\" message.
I enabled debugging on WordPress, and when I navigate to the new post page, I get:

INSERT INTO \'wp_posts\' (\'post_author\',\'post_date\',\'post_date_gmt\',\'post_content\',\'post_content_filtered\',\'post_title\',\'post_excerpt\',\'post_status\',\'post_type\',\'comment_status\',\'ping_status\',\'post_password\',\'post_name\',\'to_ping\',\'pinged\',\'post_modified\',\'post_modified_gmt\',\'post_parent\',\'menu_order\',\'guid\')
VALUES
(1,\'2019-07-14 12:53:19\',\'0000-00-00 00:00:00\',\'\',\'\',\'autodraft\',\'\',\'auto-draft\',\'post\',\'open\',\'closed\',\'\',\'\',\'\',\'\',\'2019-07-14 12:53:19\',\'0000-00-00 00:00:00\',0,0

at the top of the new post page. I also get a bunch of warnings and notices too, but I figured it\'s unlikely these are causing the problem:

I\'m new to php and WordPress, so does any WP veteran know if these are normal, or do these have to do anything to do with being unable to create new posts or save a new post draft?

突然，“发布”按钮消失了，而“新发帖”则显示“发送审核”按钮。
当点击“保存草稿”按钮时，我得到“你不被允许......”消息。
我在WordPress上启用了调试，当我导航到新帖子页面时，我得到：</ p>
\\ n

  WordPress数据库错误：[第1行的\'post_date_gmt\'列的日期时间值不正确：\'0000-00-00 00:00:00\']

  INSERT INTO\'wp_posts\'（\'post_author\'，\'post_date\'，\'post_date_gmt\'，\'post_content\'，\'post_content_filtered\'，\'post_title\'，\'post_excerpt\'，\'post_status\'，\'post_type\'，\'  comment_status\'，\'ping_status\'，\'post_password\'，\'post_name\'，\'to_ping\'，\'pinged\'，\'post_modified\'，\'post_modified_gmt\'，\'post_parent\'，\'menu_order\'，\'guid\'）

位于顶部 新帖子。 我也得到了一堆警告和通知，但我认为这不太可能导致问题：</ p> 
 警告：在wp-admin \\ includes中从空值创建默认对象 第475行\\ post.php 

注意：未定义的属性：第64行的wp-admin \\ post-new.php中的stdClass :: $ ID

我是php和WordPress的新手，任何WP都是 老手知道这些是否正常，或者这些是否与无法创建新帖子或保存新帖子草稿有关？</ p>

网友观点：

I\'ve resolved this issue by changing all core files inside WordPress since that inside the files can be a malware. This is not a solution for the custom-designed theme because then is probably some mistake inside the theme. 
You can download a fresh new install, remove the wp-content folder, and wp-config.php file and just merge via FTP/SFTP to your root folder where is the WordPress install.
I would suggest you create a backup first.
