Earlier It was working fine, when move to cloud server, this issue raised.
I am using magento 1.5
Please anyone help me out, this issue is coming in live site.
You have not provided enough information.
First of all, magento 1.5 does not have this bug. The bug you are facing is likely to come from custom work that was done on the project.
Is the site using an ajax cart? if so, follow the add to cart methods it uses.
Was there any custom work done on the cart controller?
other than that you really have not given enough information for people to attempt to answer this.
