Can not login with correct username and password

Question

I can not access to Wordpress dashboard with correct username and password. If I give any wrong password it's not showing any error message for the wrong. When I press on Log in button then the same page is (wp-login page) appearing. I've tried by deleting browser caches, cookies and replaced the old wp-login.php file with a fresh wp-login.php file. But it's still not working. If I reinstall the Wordpress on the domain the same trouble is appearing. I don't know where is the main problem for that. How can I solve this problem.

Answer 1

There are a few things you can try. One of them you have already tried.

Clear your browser cache (which you have stated you have tried), just make sure you cleared everything, cookies and cache.

Try deactivating all plugins by either logging in via SSH or FTP to your server and rename wp-content/plugins to wp-content/plugins_backup.

Change wp theme, it maybe an issue with your current theme. Try changing to one of the defaults like twentyfifteen.

.htaccess could be causing problems so you can once again SSH or FTP to your server and rename .htaccess to htaccess.backup.

Also check your wp-config.php making sure that your site url is defined properly, eg:

define('WP_HOME','http://example.com');
define('WP_SITEURL','http://example.com');

I hope this helps.

I've tried many methods but anyone couldn't worked for me. So tried to solve by myself. I've discovered a solution. First, I cleared Browsing Data (cookie, cache and others) by pressing Ctrl+Shift+Delete. Secondly, Exit from the browser. Third Step, Disconnect the internet connection. Fourth Step, Clean my PC using a cleaner software (I used wise care 360). Sixth, Connect the internet and successfully access to Wordpress dashboard.

Answer 3

This one worked for me. It requires specific knowledge of PHPMYAdmin and wp_config.php

1. Open your MySQL database in PHPMyAdmin
2. Go to your wp-config.php file
3. In wp-config, find this line: $table_prefix = 'your_prefix'; change 'your_prefix' to something new, for example 'your_new_prefix'.
4. Visit any page on your site. Wordpress will start a new installation process. It will create a whole new set of database tables. During installation, type in your CURRENT user name and password.
5. In PHPMyAdmin, open your [your_new_prefix]_users table, copy your password hash from the user_pass column.
6. Open your your_prefix_users (i.e. the old) table. Find your user and paste the password hash you have copied to its user_pass column.
7. In wp_config, type in your previous prefix. Now you should be able to log in properly.
8. Delete temporary tables from your database.

Takes like 3 minutes. Especially helpful if you don't get your password recovery emails for some reason. Warning: some of the steps can not be undone. Back up before you do anything.
