求助：使用000webhost+wordpress建站，现在无法登陆了

如题，每次登陆网站后台时直接跳转至000webhost的错误页面，登陆cpanel后，提示好像受到什么攻击，让修改一些东西。cpanel显示的信息如下：

Potential WordPress problem (Brute Force attack against WordPress websites)
We have monitored on-going brute-force attack against WordPress websites, in order to keep your WordPress website secure, we recommend you do the following:

1. Please change your password for WordPress admin area.

2. Go to your cPanel > File Manager and find your wp-login.php file.

Temporary rename wp-login.php file (for example into wp-login1.php).

You need to change a line in your wp-login.php to reflect the change to the file name. Its line 671 where the form action refers to wp-login.php

————————-Update—————————

wp-login.php is temporary disabled because of huge brute force attack. Please rename wp-login.php to something else.

小弟不知道如何修改，求大神予以指导！先行谢过。
