Style missed on "Added to your cart" pop-up

Hi all.
For some reason, the style in the pop-up window "Added to your cart" is missed.
I've come back to the demo site to check the style and the pop-up show two buttons.

3. the ftp data (host, user, password)
4. link to this thread

Hi!
I've sent to you the credentials via PM.
Thanks!

I didn't receive a PM from you. Please send it again.

Sorry, I've already sent again.

The style you have posted in first post is taken from 2.x version of Joomla and VM. Enabling "Use Fancybox" option fixed missing image issue and information box now looks as it should (VM3.x style).

I've got the same issue, using the latest versions. The fancybox checkbox is on. Still doesn't work.

The strange thing is, when I restore a backup of the website on my local machine, the pop up (fancybox) works. With same settings...

Can someone please help me out to fix this? There must be a difference between my local machine and the webserver...
