Troubleshooting an Update Message Validation Issue Error
An Update Message Validation Issue notice may display at Utilities > Update WHMCS with the following message:
The Automatic Updater utility can display important messages before initiating the update process. A digital cryptographic signature protects them. This message indicates that the cryptographic validation is failing.
There are four potential causes of this:
- The CA bundles are out of date and the system cannot validate the certificate.
- OpenSSL is out of date.
- A PHP configuration is causing the cryptographic validation to fail.
- Your server is the target of a Man-in-the-Middle (MITM) attack.
To resolve this issue:
- Go to Utilities > Update WHMCS and click Check for Updates. This will cause WHMCS to reevaluate the available updates and may complete the cryptographic validation.
- Ensure that OpenSSL is up to date on your server. Work with your server administrator or hosting provider to make this change. After updating OpenSSL, repeat step 1 above.
- Ensure that the root CA bundles on your server are up to date. After updating the root CA bundles, repeat step 1 above. For more information on updating root CA Bundles on your server, see Troubleshooting a File could not be downloaded error.
If the problem persists after performing these steps, WHMCS support can examine your PHP information for known problematic PHP settings or check for a MITM attack.
