Thumbnail not clickable after upgrade to VM 2.6.10

[zeisch]

Hi there,
I upgraded my VM to 2.6.10 and now the thumbnails below the main images is not clickable so that it appears big.
Does anyone know this issue?

You are using facebox.js rather than fancybox.js for the image action (as selected in Config/Templates/Activate Css Styles & Javascripts/Use Fancybox )  If you have to use facebox then you should deselect "Open additional images on main position" as that function is only available in fancybox.
