更改网站URL不会导致'；t工作Wordpress

我在Wordpress中更改网站URL时遇到问题。我不知道我做错了什么。 我从fryzjer.make4u.pl复制我的网站。 我创建了subdomendemo1.make4u.pl，并从fryzjer.make4u.pl中取出了我的文件。 当我进入demo1.make4u.pl时，将我重定向到fryzjer.make4u.pl。 我更改了文件wp-config.php中的代码

您定义了错误的常量。
wp config.php
文件的顶部应该是：

define('HOME','http://demo1.make4u.pl');
define('SITEURL','http://demo1.make4u.pl');

请注意，
WP\u HOME
变成了
HOME
，
WP\u SITEURL
变成了
SITEURL

或者，如果这对您不起作用，请尝试连接到数据库，导航到
wp_options
表，并将
home
和
siteurl
的条目调整到新URL

如果您有信心在数据库上使用SQL查询，可以使用If作为SQL查询，它将在数据库中进行全面的查找/替换：

记住：在尝试任何SQL查询之前备份数据库

您需要在所有表格中用新的域名替换旧域名。对不起，我不明白。你能解释清楚吗？我照你写的那样做，但不起作用。你知道我能做什么吗？仔细检查你的
wp config.php
中是否指向了正确的数据库-你是否切换到了新的数据库？您是否运行了所有4个SQL查询？您的数据库在wp_options->home下显示了什么？另外，
demo1.make4u.pl
没有解析为IP地址-服务器已经设置好了吗？我不知道。我如何检查它？您必须与您的提供商进行检查-询问您的主机（make4u.pl？）？无论哪种方式，这些修复都将无法工作，直到它实际应用到工作的Web服务器上。
UPDATE wp_options
SET option_value = 'http://demo1.make4u.pl'
WHERE option_name = 'home';

UPDATE wp_options
SET option_value = 'http://demo1.make4u.pl'
WHERE option_name = 'siteurl';

UPDATE wp_posts
SET post_content = REPLACE(post_content,'http://fryzjer.make4u.pl','http://demo1.make4u.pl');

UPDATE wp_posts
SET guid = REPLACE(guid,'http://fryzjer.make4u.pl','http://demo1.make4u.pl');
