If you are having trouble logging in to your WordPress Administration Panels, here are some possible solutions.

Some WordPress Plugins may interfere with the login process. Disable all of your WordPress Plugins, either through the admin panel or by removing them from the /wp-content/plugins/ folder, so they will not be recognized by the program.
Alternatively, you can rename the plugins folder to something else temporarily to something like /wp-content/pluginsXX/ and they will not be recognized. Rename the folder back to /wp-content/plugins/ once the base WordPress installation has been recovered.

Sometimes the wp-login.php file may have been corrupted or uploaded incorrectly.
// redefining user_login ensures we return the right case in the email
$user_login = $user_data["user_login"];
$user_login = $user_data->user_login;
Access your site's phpMyAdmin and edit the database carefully.

In certain cases your WordPress address URI may have been reset.
// If someone has moved WordPress let's try to detect it //if ( dirname('http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']) != get_settings('siteurl') ) // update_option('siteurl', dirname('http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']) );
Changed your WordPress address URI and cannot login nor access the database (but still can access the login page) ?
wp-login.php can be used to reset the address:
//FIXME: do comment/remove these hack lines. (once the database is updated) update_option('siteurl', 'http://your.domain.name/the/path' ); update_option('home', 'http://your.domain.name/the/path' );
In your wp-config.php try changing from:
define( 'SUBDOMAIN_INSTALL', true);
define( 'SUBDOMAIN_INSTALL', false);
If you are having a problem with secure HTTPS, change the following line in wp-includes/vars.php from:
define('COOKIEPATH', preg_replace('|http://[^/]+|i', '', get_settings('home') . '/' ) );
define('COOKIEPATH', preg_replace('|https?://[^/]+|i', '', get_settings('home') . '/' ) );
Be sure also to change the URL in OPTIONS to https://.
In some situations, your blog can be seen from inside your domain, but not outside. Following the instruction above about changing the wp-options MySQL table might still result in login failure.
In this event, double-check your wp-options table siteurl (WordPress address URL) and home (Blog Address URL) values to make sure they reference the same base externally available address; i.e., http://blog.yourdomain.com. The standard install may set them to your local (internal) host name, such as http://servername
Another issue may be if you are redirecting using .htaccess from a non-www url prefix to a www while you have the wp-options table siteurl (WordPress address URL) and home (Blog Address URL) set with non-www prefix. Consequently this would create an endless loop which you need to avoid. One way is to disable the .htaccess redirection temporarily by placing # before the line or eliminating the entries entirely and trying to Login again. Advanced users may want to adjust adjust the wp-options table siteurl (WordPress address URL) and home (Blog Address URL) through the database. Notice that this issue can also occur if you are redirecting from www to non-www but have your wp-options table siteurl (WordPress address URL) and home (Blog Address URL) set with a www url prefix.
Some firewalls (e.g., eTrust Personal Firewall) block you from logging in to WordPress. Disable your firewall and try to log in again.
If these steps fail, please indicate that you have tried all these possible solutions when posting at the WordPress Support Forum. Be sure to give details of your server setup, if you know it, including mySQL and PHP versions, as well as your operating system (OS), browser, and the WordPress version that is causing these problems.
