Hi,
We apologize for the inconvenience caused by this issue. Please ensure that you are using the latest version of Helix Ultimate, as outdated versions can sometimes cause conflicts within the template administration interface.
If you are already on the latest version and the problem persists, please let us know your Joomla version, PHP version, and the exact versions of Nestfund and Helix Ultimate you are using. We will investigate this further and get back to you with a solution as soon as possible.
Thank you for your patience and cooperation.
