我有一个WP 4.6网站，其管理员用户无法访问/WP admin，收到错误（在白色屏幕上）：

抱歉，不允许您访问此页面。

我已将设计器的完整站点SQL导出上载到phpMyAdmin中（在找到并将主机名从旧替换为新之后）。

我还在phpMyAdmin中编辑了设计器的管理员用户帐户，以将用户名、密码和电子邮件更改为我的详细信息。

之后，我收到了上面的错误。

如果我按照说明创建新用户帐户here:

Insert into wp_users:
ID – pick a number (in our example, we will use the number 4).
user_login – insert the username you want to use to access the WordPress Dashboard.
user_pass – add a password for this username. Make sure to select MD5 in the functions menu (Refer to the screenshot below).
user_nicename – put a nickname or something else that you would like to refer yourself as.
user_email – add the email you want to associate with this account.
user_url – this would be the url to your website.
user_registered – select the date/time for when this user is registered.
user_status – set this to 0.

Next we are going to have to add the values to wp_usermeta table:
umeta_id – leave this blank (it will be auto-generated)
user_id – this will be the id of the user you created in the previous step. Remember we picked 4.
meta_key – this should be wp_capabilities
meta_value – insert this: a:1:{s:13:"administrator";s:1:"1";}
Insert another row with the following information:
unmeta_id – leave this blank (it will be auto-generated)
user_id – this will be the id of the user you created in the previous step. Remember we picked 4.
meta_key – this should be wp_user_level
meta_value – 10

如果我上传了WP 4.6的新副本，我已经从Wordpress下载了。org，问题仍然存在。

如果清除浏览器缓存，问题仍然存在。

如果我将/wp-content/plugins重命名为/wp-content/plugins。旧的，问题仍然存在。

是方法listed here 在phpMyAdmin中添加新管理员用户的正确方法是什么？

如果我改变wp_capabilities 对于来自的原始或新管理员用户a:1:{s:13:”administrator”;s:1:”1″;} 到a:1:{s:13:”administrator”;b:1;} 正如上面URL上的一条评论所指出的，问题仍然存在。

感谢您的帮助。
