Contextual links (gear menu) not showing

I have an issue with the contextual links on the Antonelli theme.
The gear menu is missing.
On my other themes, the gear is working like it should be.

After some research i found this in the contextual link documentation:
"Displaying contextual links

When using default rendering, the normal teaser view will embed the contextual links on nodes for you.

If using a customized theme, your node template should include the normal renderable elements found in core's node.tpl.php. Specifically, the contextual links are provided by the line"

<?php
       print render($title_suffix); 
?>

But there is no node.tpl.php in the sites/all/themes/antonelli folder
So i copied the bartic theme node.tpl.php and added it to a (new created) sites/all/themes/antonelli/templates folder.

I also cleared all cache of drupal and my browser.
But it's not working.

Any suggestions?
