Wordpress登录错误wp-admin err_too_many_redirects

Question

我遇到wordpress登录问题。我正在使用wordpress 3.9，突然之间我无法登录我的管理员或任何帐户。当我输入https://lifesymb.com/wp-admin/时，我收到以下错误。

This webpage has a redirect loop 
The webpage at https://example.com/wp-admin/ has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.

Error code: ERR_TOO_MANY_REDIRECTS

我尝试清除我的cookie，尝试在另一台计算机上尝试更改.htaac​​cess，如下所示

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]


RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d


RewriteRule . /index.php [L]
</IfModule>

# END WordPress

并尝试了很多方法，但我不成功，但我的网站显示良好，我的网站使用SSL。所以任何人都可以帮我解决这个问题。

谢谢
