Somehow crashed the module Sample Mosaic Portfolio.
Nothing is displayed now. Is there a way to restore this module?
Also an error is displayed "Fehler The parameter "roksprocket.layouts..service" must be defined."
Whats wrong?

Url please and more info:
1.) Did you installed the quickstart?
2.) Joomla version
3.) Any other extensions installed
4.) All extensions are up to date?

Yes I have installed the whole thing via quickstart
Joomla 3.4
Local Xampp Server
All extensions are updated as well as joomla.

I had the template and the demo contence running correctly. I logged in in the frontend and changed the Title of
"Sample Mosaic Portfolio" . Save it. Then the module did not work.

Only name changing gives no error.
Maybe you did a mistake, but I dont know which, coz I have no access to your Joomla.
Please download the newest version of roksprocket and install the extension again with uninstalling the old one.
demo.rockettheme.com/joomla-extensions/roksprocket/

which one should i uninstall??
