折腾：
【未解决】crifan.com的WordPress无法登录在wp-login登录页死循环
期间，去登录后台数据库中看看
看到：wp_login_fails
有很多登录错误的记录
去看看phpMyAdmin
Possible fix for sudden redirect loop at wp-login with reauth=1 | WordPress.org
和我现象很像：突然出现这种：wp-admin，进入wp-login，结果无限死循环再wp-login
http://mysite/wp-login.php?redirect_to=http%3A%2F%2Fmysite%2Fwp-admin%2F&reauth=1
去配置页面中，本身有：
siteurl=https://www.crifan.com home=https://www.crifan.com
配置没问题。
去找到那人说的：
WordPress数据库-》wp_usermeta-》session_token
但是我此处是：
session_tokens
把当前值拷贝出来，供研究：
session_tokens =

删除之前，格式化看看
看起来就是：
ip
ua
等值
去删除：
再去试试登录
结果是：
问题依旧
去登录，还是跳转回登录页
不过回来看数据库，果然多了一条：
a:1:{s:64:"d6122d6b43540f9c980dbf0f5e6fed5db2e5c4d7ce03c1823c31cd770e05636c";a:4:{s:10:"expiration";i:1604238874;s:2:"ip";s:12:"103.88.46.69";s:2:"ua";s:121:"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36";s:5:"login";i:1604066074;}}其实就是正常的，已经登录的相关信息
按道理应该是没问题的才对。
