I am currently taking the developer of a page based on CS cart. Previous programer (developer) disabled notifications on first page, so when you add product to cart, popup does not appear, only white overlay over the page, which stays as long as it is specified in admin panel (ex. 3s).
Also, if you login on first page, and input wrong password, there is no notification for that, like on the standard login page…
See screen shots (1 = white overlay, 2= password promt on standard login page, ):
Thank you for your help!
