Currently I am working on a e-commerce website. When I visit the site for first time they are displaying a popup, like discounts or signup etc... while writing my scripts I wrote code for waiting for the popup and closing the popup. But after some days the developers removed the popup ad's. So now my script is failing too find the popup as per coding. How can I handle such a scenario?
