Apolozy for the inconvenience and the delayed response due to the weekend.
The issue you encountered was caused by changes in the latest Joomla 5.2.4 update, which introduced syntax modifications that affected some of our templates. We have addressed this and released an update. Kindly update the Helix Ultimate Framework to the latest version to resolve the issue.
Regarding the missing settings, we sincerely apologize. Unfortunately, we do not have control over this. If you have a working backup on your local machine or server, you can install the backup, export the template settings, and then import them into your live site.
Thank you for your understanding and patience.
Best regard
