Yes, we’re planning to upgrade all Helix3 templates to Helix Ultimate. Hopefully, they will be converted to Helix Ultimate soon.

Thank you!

Hello Taco,

The error “Class ‘Joomla\Component\Installer\Administrator\Service\HTML\Updatesites’ not found” likely indicates a missing or corrupted file. Try these steps:

  1. Ensure Joomla and all extensions are up-to-date.
  2. Reinstall core Joomla files to fix missing components.
  3. Verify your PHP version is compatible with Joomla and the Finance extension.

For the template styles looking different, check your template settings under “Extensions > Templates” and ensure compatibility between your template and the Finance extension. Clear cache as well to rule out display issues.

Let me know if you need more help!

Best regards,
