Troubleshooting Phone Number Errors after updating

Error Details

After applying the 7.4 update, you may encounter an error message relating to phone numbers.

The error could manifest in different ways, possibly an error when clients attempt to update their profile details, or when attempting to register or otherwise manage domain names.


The cause is an after-market customisation which is incompatible with the new Phone Number UI.


Please contact the vendors of your after-market customisations/tempaltes for an update which is compatible with version 7.4.


A workaround is available by disabling the new Phone Number UI. In your WHMCS Administration Area:

  1. Navigate to Setup > General Settings
  2. Click the Localisation tab
  3. UNtick the Phone Numbers checkbox
  4. Click Save Changes
