WordPress login failed? These 5 steps will help you solve it!

WordPress is a widely used open source content management system, and many webmasters choose to use it to build their own websites. However, sometimes when using WordPress, you will encounter login failure problems, which brings trouble to administrators. Today we will introduce you to the five steps to solve the WordPress login failure problem and provide specific code examples, hoping to help you.

Step One: Confirm Username and Password

One of the most common reasons for login failure is that the entered username or password is incorrect. Before logging in, please double-check that the username and password you entered are correct. You can also try using the "Forgot Password" feature to reset your password.

Step 2: Clear cache and cookies

Sometimes the browser’s cache or cookies may cause login problems. You can try clearing your browser's cache and cookies, and then try logging in again.

Code example:

// 清空浏览器Cookie
setcookie('wordpress_logged_in', '', time() - 3600, '/');

Step 3: Check the WordPress configuration file

Sometimes the reason for login failure may be due to errors in the WordPress configuration file. Please check the wp-config.php file to ensure that the database connection information, authentication key and other information are correct.

Code example:

define('DB_NAME', 'your_database_name');
define('DB_USER', 'your_database_username');
define('DB_PASSWORD', 'your_database_password');
define('DB_HOST', 'localhost');

define('AUTH_KEY', 'your_auth_key');
define('SECURE_AUTH_KEY', 'your_secure_auth_key');
// 其他认证密钥...

Step 4: Disable plug-ins and themes

Sometimes plug-in or theme conflicts may also cause login failure. You can try disabling all plugins and using the default theme, then enabling them one by one to find out which plugin or theme is causing the login issue.

Code sample:

// 禁用所有插件
update_option('active_plugins', array());
// 使用默认主题
update_option('template', 'twentynineteen');
update_option('stylesheet', 'twentynineteen');

Step 5: Reset password

If none of the above steps can solve the problem, you can try to reset the password directly through the database. Log into your WordPress database using phpMyAdmin or another database management tool, find the wp_users table, edit your user data row, and change the password field to the MD5 hash of your desired new password.

Code sample:

UPDATE wp_users SET user_pass = MD5('new_password') WHERE user_login = 'your_username';
