Automatic Updater
The Automatic Update utility allows admin users to update WHMCS quickly and easily in just a few clicks.
Contents
System Requirements
For updates to be able to be completed successfully, the following requirement must be met:
- 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
Checking for Updates
New updates are checked for automatically at periodic intervals.
When an update becomes available, a notification will appear in the top left corner of admin area.
In addition, you can check for updates on-demand by navigating to Utilities > WHMCS Update and clicking the Check for Updates button.
If a newer version is available, the Latest Version display will update to show the version available to update to. The status of the update check will also be displayed top right as a notification.
Performing an Update
To perform an update, navigate to Utilities > Update WHMCS and click the Update Now button (pictured above).
You will then be guided through the update process. The update process can take anywhere from 30 seconds to a few minutes to complete.
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.
For most users, we recommend choosing the Stable channel which will only apply Stable updates to your installation.
| Channel | Description |
| Stable | Recommended for most installations of WHMCS, the Stable channel will track the latest stable version that has been released. |
| Release Candidate | Subscribing to the Release Candidate channel will allow you to receive releases after beta testing but before they are released to the Stable tier. |
| Beta | Subscribing to the Beta release channel will allow you to receive the very latest versions of WHMCS. This tier should only be selected for development and test based installations. |
| Current Version | Subscribing to this channel will restrict you to only receiving maintenance updates for the major/minor version that is currently installed. For example if the installed version of WHMCS is 7.0.0-GA, admins will be offered upgrades to 7.0.1-GA and 7.0.2-GA, but not 7.1.0. |
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.
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.
Permission Errors
Permission errors may manifest themselves in the tblupdatelog table as the following:
[WHMCS\Exception] Failed to perform early file copy during WHMCS file relocation: init.php
or
[RuntimeException] /path/to/whmcs/whmcs does not exist and could not be created.
These kinds of file permission and ownership issues are multi-faceted and dependant upon the individual server configuration. However for a standard cPanel server using the suPHP PHP Handler an appropriate posix file permissions permissions would be:
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. Eg. On a cPanel box where the web-root is located at /home/david/public_html/, files should be owned by david, and the group should be david.
Finally, the owner and group of the PHP process seeking to take action should be the same as the user directory name. Eg. On a cPanel box where the web-root is located at /home/david/public_html/, PHP process owner and group should be david.
Other types of server and PHP handlers may have different configuration requirements, the above is intended as a guide for one particular possible combination only.
Curl 77 Error
CURL77 errors may manifest as the following in the tblupdatelog table:
[WHMCS\Installer\Composer\ComposerUpdateException] Failed to get certificate metadata from keyserver. Error: Unable to download file from URL: https://pki.whmcs.com/certs.json Message cURL error 77: Problem with the SSL CA cert (path? access rights?) update [--prefer-source] [--prefer-dist] [--dry-run] [--dev] [--no-dev] [--lock] [--no-plugins] [--no-custom-installers] [--no-autoloader] [--no-scripts] [--no-progress] [--with-dependencies] [-v|vv|vvv|--verbose] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--ignore-platform-reqs] [--prefer-stable] [--prefer-lowest] [-i|--interactive] [--root-reqs] [--] []...
This error indicates that the server was unable to connect to the WHMCS update server because the security of the connection could not be verified. The connection is secured using SSL certificates and to verify the certificate your server needs up-to-date root certificates to know which to trust.
Please work with your server administrator or hosting provider to ensure the root CA bundles are fully updated on your server.
