The Automatic Update utility allows admin users to update WHMCS quickly and easily in just a few clicks.

You can access this feature at Utilities > Update WHMCS.

For more information on the way in which updates change files, see Updater File Changes.

System Requirements

For automatic updates to be possible, the following system requirements apply:

• A PHP Memory limit of at least 128MB
• At least 250 MB of free disk space
• PHP setting allow_url_fopen enabled
• PHP max_execution_time in excess of 60 seconds
• PHP Zip Extension or the proc_open PHP function enabled
• PHP setting open_basedir to include entire WHMCS docroot

Configuring Your Update Settings

Choosing an Update Channel

The WHMCS automatic updater allows you to choose an update channel that defines the type of updates you will receive. The update channel setting determines the least stable version you are willing to update to:

Patch and Maintenance Release Updates

• If you are on a version that is in Long Term Support and a patch is issued for that series, you can use the Updater to apply the patch and remain on that series.
• To do this, select the Current Version update channel as described above.
• You many need to click Check for Updates after any setting changes in order to refresh the available version displayed within the page.

Setting a Temporary Update Path

A temporary path is required for staging of files during an update. For security reasons it is recommended that this directory be located outside the public doc root, similar to the attachments, downloads and templates_c directories. The path must be an absolute path (i.e. /home/whmcsuser/tmp instead of ~/tmp) and must be writable by the user that is running PHP.

Setting a Maintenance Message

This option can be used to set a message that will be displayed to both other admin and client users whenever an update is in progress.

Checking for Updates

The system automatically checks for updates periodically. When an update becomes available, a notification will appear in the Admin Area.

Manually checking for updates

You can check for updates on-demand by clicking Check for Updates.

You may need to do this to see recent releases prior to the next automated check.

For Owned licenses, the version that this fetches will be the version of WHMCS that was available when your Support and Updates subscription was active. Downloading the latest version of WHMCS requires an active Support and Updates subscription.

Performing an Update

To perform an update:

1. Make certain that your server meets the system requirements and review the Release Notes for any important notices and information.
2. Make a full backup of your current installation.
3. In WHMCS, click Update Now.
   This option only displays if an update is available for your current update channel.
4. Follow the prompts to complete the update process. The update process can take anywhere from 30 seconds to a few minutes to complete.

If you have custom template files you will also need to review and make any necessary changes to your custom templates using the information provided in the Template Changes section of the Release Notes.

Troubleshooting

The actions performed by the Automatic Updater are recorded in the tblupdatelog table within the WHMCS database. To troubleshoot upgrade problems it is useful to review this table for the most recent entries (the highest id values). A tool such as phpmyadmin can be used to browse to the table contents.

For additional guides to troubleshooting auto-update problems, see Updating and Upgrading New Installation Prompt.

Please ensure you have selected a valid Update Channel and then try again

Receiving this error message in the cron job report email or activity log, indicates that an Update Channel setting needs selecting. To do this, click Configure Update Settings.

Next select one of the four available update channel options, and Click Save Changes. The options are described above.

Permission Errors

Permission errors in the update log may resemble the following examples:

• [WHMCS\Exception] Failed to perform early file copy during WHMCS file relocation: init.php
• [RuntimeException] /path/to/whmcs/whmcs does not exist and could not be created.
• failed to open stream: Permission denied
• Apply update dry-run detected 1 permission issues

The exact file permission and ownership issues will depend on the individual server configuration. However, for a standard cPanel & WHM server using the suPHP PHP handler, the following configuration would be an appropriate POSIX file permissions:

• configuration.php — 400
• /crons/pipe.php — 755
• All other PHP files — 644
• All directories — 755

The file ownership and group should be the same as the user directory name. For example, on a cPanel & WHM server with a web root at /home/username/public_html/, the username user would own the files and the group would also use the name username.

Finally, the owner and group of the PHP process must be the same as the user directory name. For example, on a cPanel & WHM server with a web root at /home/username/public_html/, the PHP process owner and group would both be username.

Other types of server and PHP handlers may have different configuration requirements.

Unable to connect to the WHMCS Update Server

You may see this error when you attempt to perform an automatic update or it may appear in the Activity Log section at Configuration () > System Logs or, prior to WHMCS 8.0, Utilities > Activity Log. It indicates that your server could not connect to the WHMCS update server.

To resolve this, attempt the following cURL connections from your server's command line:

If these commands are successful, they will return StatusCode: 200. If they do not, ask your hosting provider or system administrator to investigate the connectivity problem between your server and the WHMCS update server.
