I am facing a Login problem since a few days when I am trying to login in my website. please help me about that.
Usually, this happened when you installed a plugin that is incompatible with your WP blog/ themes etc. Whatever, it is. Follow this small instruction. 1. Log in to your FTP 2. Search your plugin in WP-content inside public html 3. Right click plugins and rename it as plugins-sample 4. After Login back to your WP admin, rename plugins-sample back to plugins. 5. Activate each of the plugin one by one until you find out the culprit plugin. If you knew what have you done recently, you might know what was happening. That's it. Not too hard.
Open your cpanel > PHPmyaadmin > wp_user option > and change the PASSWORD keeping MD5 option and try LOGIN IN to WP. This will work 100%
There's several options to reset your WordPress password in such a case. Have a look here: http://codex.wordpress.org/Resetting_Your_Password
phpmyadmin method is the best and 100% As it was said - find yourself in db, delete MD5 hash and paste another MD5 hash. On passcracking.com you can type in new password and MD5 hash will be generated so you can pste it in db save and login to your lovely blog
Yes this is the best method. You can also use the Emergency Password resetting Script mentioned here: http://codex.wordpress.org/Resetting_Your_Password
