我的网站的一个wp管理员不可访问，但网站前端正在加载。这发生在我第二次从新服务器访问站点之后。起初什么都没发生，我可以登录到仪表板。然后，在我注销并第二次尝试登录后，会发生此错误。访问mysite时。com/wp admin页面显示

The page isn\'t redirecting properly.Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

在public\\u html/error\\u日志中：

PHP Warning:  require(/home/mysite/public_html/wp-includes/pomo/mo.php) [<a href=\'function.require\'>function.require</a>]: failed to open stream: Permission denied in /home/mysite/public_html/wp-settings.php on line 76
PHP Fatal error:  require() [<a href=\'function.require\'>function.require</a>]: Failed opening required \'/home/mysite/public_html/wp-includes/pomo/mo.php\' (include_path=\'.:/usr/lib/php:/usr/local/lib/php\') in /home/mysite/public_html/wp-settings.php on line 76

cpanel error\\u日志显示：

Permission denied: /home/mysite/public_html/wp-admin/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable

htaccess具有644权限。但我把它改成了775和755，并检查了一下。同样的情况也会发生。原因可能是什么？如何解决这个问题？
