Thanks for the demo link. I will look at it and discus to my boss...
Ps: I had been sent to you some message on this system almost a month ago. https://forums.cubecart.com/messenger/25197/ did you see my message about fully managed VPS Server
Can you provide us with a backend demo? We need to see the 'skin configure plugin' and we need to use left and right side column on the skin. Left side for a menu, right side for the additional information like contact us, quality certification etc.
And also we have another web site with CubeCart Version: 4.4.2. Do you have responsive skin for suitable for this version?
