Start Troubleshooting

If you do not know the cause of a problem, troubleshooting helps you learn more about it. We recommend trying basic steps to gather information before you contact WHMCS support.

Email Importing

Email importing retrieves customers' email replies to support tickets. You can use POP3, IMAP, Google®, or Microsoft® for email importing.

Email Piping

Email piping automatically imports email replies that a support department email address receives into the corresponding support ticket.

Sync Accounts

Sync Accounts matches your records in WHMCS to your server's accounts and can help you resolve many account- or service-related issues.

The configuration.php File

The configuration.php file contains many of the most important and sensitive configuration details for your WHMCS installation.

Notifications

WHMCS integrates with popular team communication apps, including Slack® and HipChat™, to allow WHMCS to notify you in real time as events occur.

Application Links

Application Links use WHMCS Single Sign-On to allow users to seamlessly access WHMCS from the cPanel or WP Squared control panels.

Database Status

You can monitor and manage your WHMCS installation's database, including optimizing database tables and manually downloading database backups, from within the WHMCS Admin Area.

Enable Error Reporting

For many types of issue, the first step in troubleshooting is enabling WHMCS's error reporting system.

Errors in WHMCS

WHMCS makes troubleshooting easier with built-in error handling.

Module Queue

The Module Queue list allows you to quickly find and retry failed automated actions.

System Cleanup

WHMCS allows you to prune logs to reduce the size of the database and reduce disk space.

System Logs

WHMCS logs all activity, admin logins, gateway communications, sent and received email communications, and domain lookups.

Log Tab

The Log tab in the Client Profile lists entries from the Activity Logs that relate to the client.

Optimize Performance

As your database size increases, you may experience slower page loads and other speed-related issues. Optimizing your database and reducing unnecessary data can help WHMCS run faster.
