This "black page after login" is almost always a server-side PHP fatal error (the WordPress "white screen of death"), not a browser-password issue. 's phpMyAdmin/password-check and 's cache/safe-mode tips are sensible first steps, but because you reinstalled and the problem persisted, focus on server-side troubleshooting: plugin/theme code, PHP errors, file permissions, or a corrupted core file.

Do these in order, making a full backup first:

  1. Turn on WordPress debugging so errors are recorded (do not leave this on in production):
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

Check wp-content/debug.log and your host's PHP error logs for the exact fatal error. See Debugging in WordPress and a practical WSOD guide at .

  1. Disable all plugins quickly by renaming wp-content/plugins (via FTP or file manager). If login works, restore the folder name and enable plugins one-by-one to find the culprit.

  2. Temporarily switch the active theme by renaming its folder (forces WordPress to fallback to a default theme). A broken functions.php in the theme often causes admin-side crashes.

  3. Re-upload fresh core WordPress files (all files except wp-config.php and wp-content) to rule out corrupted core files. Check or reset .htaccess and confirm siteurl/home values in wp_options if redirects occur.

  4. Check file permissions (directories 755, files 644) and PHP memory limits; increase memory if needed:

define('WP_MEMORY_LIMIT', '64M');

If logs show unusual file edits or unknown admin users, treat it as a compromise and involve your host. If these steps fail, provide the exact PHP error from the debug log when asking for further help. See Changing File Permissions for permission guidance.

Your blog might be compromized? If you can get to your databse, do the following:

Use phpMyAdmin to access the database then look at your WordPress database table wp_users to see what users and email addresses are on file. You should see your admin user there. Check the field for your email address and make sure it is correct and save it. Then go back to the admin login and click forgot password and the system should shoot you out a temporary password.

If you can't do that, contact your host and ask them to help you access your database.

<------------ doesn't know anything about Wordpress, but if you're accessing it through a browser.

Trying clearing your cache, reseting the browser, and/or entering safe mode (to prevent add-ons/plugins from running).
