Fix underlying cause of failure
WordPress updates can fail due to timeouts, permission issues, or conflicts. Sometimes they leave your site in maintenance mode or break it entirely. Here is how to recover.
Failed updates leave a .maintenance file in your WordPress root. Connect via FTP and delete this file. Your site should immediately come back online.
Updates fail if the server runs out of space. Check your hosting disk usage. Clean up old backups, logs, or unused files if storage is full.
Add to wp-config.php: define('WP_MEMORY_LIMIT', '256M'); And in .htaccess: php_value max_execution_time 300. Updates can timeout on limited servers.
Download WordPress from wordpress.org. Extract and upload wp-admin and wp-includes folders via FTP, overwriting existing files. Do not overwrite wp-content.
Download the plugin from wordpress.org/plugins. Delete the old plugin folder in /wp-content/plugins/ via FTP. Upload the new plugin folder. Reactivate in admin.
WordPress needs write permission to update. Folders should be 755, files should be 644. The wp-content folder and its contents need to be writable.
If updates broke your site badly, restore from a pre-update backup. Then update more carefully, one item at a time, testing after each.
