Roksmart Template Error with Helix Framework

Hi Guys,

I installed a “only template” Version of the Roksmart Template and the Helix Framework which is delivered with the template.
The frontend is working after installing the Helix Framework, but I can’t make changes in the template style. None of the Buttons are workin (Save, Save and Close, Save as Copy, Close). I only come back to the backend interface by modifying the URL to http://hompage/administrator.
Every button in modules or menus are working. If I uninstall the HelixFramework the buttons work in template styles to, but i need the framework that the template is working.

Joomla Version 3.8.2
Helix Framework 2.5

Greetings,

Michael
