WordPress cannot be logged on to the background. The following error occurs: wp-admin/& reauth = 1.

Just now, a customer's WordPress blog forgot his password, so he changed the password through FTP. However, after entering the correct username and password in the background, he still cannot log on, the logon address is % 2Fwp-admin % 2F & reauth = 1.
Example: h/wp-login.php? Redirect_to = http % 3A % 2F % 2Fwww.fengzx.com % 2 Fblog % 2Fwp-admin % 2F & reauth = 1

Google Baidu had not found a solution for a long time, but later remembered that when the password was changed through FTP, the modified topic functions. php file did not delete the code for changing the password:

The code is as follows:	Copy code
Wp_set_password ('password', 1 );

After this code is deleted, you can log on to the background.
