Disable MySQL Strict Mode

You must disable MySQL® Strict Mode (sql_mode) to successfully run a self-hosted WHMCS installation. We recommend disabling this immediately after you finish installation.

Encrypt Your MySQL Connection

You can configure WHMCS to use an encrypted MySQL® database with your self-hosted WHMCS installation. This requires additional steps to add settings to your configuration.php file.

Migrate Local Storage

You can migrate your data between local storage locations, or migrate data from an existing location like an Amazon S3™ bucket.


Restore the WHMCS Database

If a serious problem occurs on a self-hosted WHMCS installation, you can restore your WHMCS database from a recent backup.

Set Up Amazon S3 Storage

WHMCS supports using Amazon S3™ and Amazon S3-compatible services as storage providers. After you create an Amazon S3 bucket, you can configure it as your storage location.
