What to do before repairing WordPress database

Before proceeding with any database repair on your WordPress site, it is essential to follow a series of steps to ensure that the process is safe and efficient. Here’s what you need to do:

Backup the database: Use plugins such as UpdraftPlus, WP-DB-Backup or the backup tools provided by your hosting to create a backup of your database. Be sure to store this copy in a safe place, preferably outside of your site’s server.

Backup site files: In addition to the database, back up all site files (themes, plugins, images, etc.). This can be done manually via FTP or by using a backup plugin.

Disable unnecessary plugins:

Disable all plugins that are not needed during the repair process. This can prevent conflicts and ensure that the repair is performed without interruption.

Enable maintenance mode:

Put your site in maintenance mode to let visitors know that you are working on the page. You can do this via plugins such as “WP Maintenance Mode” or by simply adding a maintenance.php file to your WordPress root directory.

Verify database credentials:

Make sure the database credentials (database name, user, password and server) in your wp-config.php file are correct. Incorrect credentials can be the cause of connection problems.

Review error logs:

Before you begin repairs, review your server and WordPress error logs. This can provide you with valuable information about the cause of problems and help you focus your repair efforts.

Prepare the necessary tools:

Make sure you have access to tools such as phpMyAdmin, WP-CLI or any other software you plan to use during the repair process. Familiarize yourself with their use if you haven’t done so before.

Consult the official documentation:

Review the official documentation from WordPress and your hosting provider for specific guidelines and recommendations on how to handle database repair. This may provide you with additional steps or specific precautions you should take.
