System Health Status
The Health & Updates page provides an overview of the WHMCS installation and system environment status.
It will highlight any potential configuration or security related issues that may need your attention.
It also allows you to check if any updates are available for your currently installed WHMCS version, as well as providing quick and easy access to the Changelog and Release Notes for it.
An overview of the checks performed and the purpose of each is provided below.
System Cron Tasks
Checks that the system cron has run to completion within the last 24 hours. If this reports a failure, it indicates that either the cron is not running (invalid cron command, file permissions, cron folder path, etc...) or that the cron is failing to complete successfully.
If this check reports a problem, you should begin by checking your cron command configuration and the activity log within WHMCS. For further assistance, please contact our support team.
Insecure Permissions Check
Ensures that key files and directories have appropriate permissions. Will alert you to ownership mismatches and/or permission levels that are higher than required for day-to-day operation of the system.
Required PHP Extensions
Checks for any PHP extensions required by WHMCS to operate and will alert you to any that are missing. Should any be reported as missing, you should recompile PHP with the missing extensions included.
Recommended PHP Extensions
Checks for the presence of recommended PHP extensions. While not strictly required, this will alert you to any extensions which are not available in your environment that are either required by certain addons/modules or that can help provide improved performance.
Required PHP Functions
Checks for any PHP functions that are required for WHMCS to operate and will alert you to any that are disabled. If you see any functions reported here, you should check for the presence of them in the php.ini configuration file disable_functions setting and remove them.
PHP Memory Limit
Checks the memory limit setting in your PHP environment and will alert you when it is too low. Will alert you by way of a failure level alert when below the minimum required value and a warning level alert when above the minimum but below the recommended value. For more details on the required memory limit, please refer to the System Requirements page.
Alerts you if error reporting is enabled in your environment. While useful for development and debugging situations, in production, we strongly recommend having error reporting disabled for security reasons.
PHP Error Levels
Alerts you if the error reporting level is set to a very high level. We recommend only logging certain error types.
Checks your PHP Version. Will alert you if your current PHP version has reached End of Life and is no longer supported by the PHP Group.
Customising Default Paths
Checks for the existance of custom directory paths. You can customise some of the default directory paths in WHMCS to make it more difficult for malicious users to find them. This check will alert you if any directories that support customisation have not been customised.
Using Default Templates
Alerts you if any template settings are set to a template of a default name which could be an indication of customisations having been made to a default template. This can result in customisations being lost at the time of the next upgrade.
Installed cURL Version
Checks the installed curl version and alerts you if your version is known to have any vulnerabilities.
SSL Support in cURL
Checks to ensure that the curl library present in the PHP environment has SSL support which is required for normal WHMCS operation and many of the modules which come with WHMCS.
Checks if all database tables and columns use utf8_unicode_ci collation. This is recommended to ensure correct searching and sorting for all international characters.
PHP Session Support
Alerts you to any issues with the PHP Session configuration in your PHP environment.
Secure TLS Support in cURL
Checks to ensure that the curl library present in the PHP environment supports secure TLS versions (TLS v1.1 and v1.2). With many payment vendors phasing out legacy SSL/TLS protocols in accordance with PCI DSS recommendations, this check will help to stay up to date with newer standards.
