update of helix ultimate

Apolozy for the inconvenience caused. The issue you're experiencing is due to syntax changes introduced in the Joomla 5.2.4 update.

To resolve this, please update your Helix Ultimate Framework to the latest version. Kindly note that some settings may be lost during the update, as you mentioned. To prevent any data loss, I recommend exporting your current template settings from the working site and importing them into the affected site. https://www.joomshaper.com/documentation/helix-framework/advanced#import-and-export
