Automatic Updating

If you are running WHMCS 7.0 or later, you can use the built-in Automatic Update utility.

Simply navigate to Utilities > Update WHMCS to begin the process.

  If the update was released recently, you may need to click the Check for Updates button before the update will show as available.
WHMCS v7.5.1 requires ionCube Loader® 10.1 or higher. The Automatic Updater verifies this requirement for you in v7.4.2. If you are using the Automatic Updater and are not yet on v7.4.2, then you will not see the v7.5.1 update but only v7.4.2. Use the Auto Updater to first update to v7.4.2. After this, v7.5.1 will viewable and the Automatic Updater will be able to verify all requirements before proceeding to this latest version.

For more information about the Automatic Updater and troubleshooting please refer to the Automatic Updater documentation.

Release Notes

  • Encoded File Loading - In WHMCS v7.5.1 you have the option to control the Encoded File Loading feature. This feature was introduced in v7.5.0 to mitigate the possibility of fatal errors resulting from the inclusion of incompatible ionCube-encoded files. Disabling this feature may be needed for some custom ionCube files. For example, the ionCube Encoder product currently produces files whose embedded content does not follow the same conventions of other encoded files and thus may trigger a negative evaluation.
