karenderia - Mobile APP

 I) In my app, the featured restaurant and All restaurant section is showing nothing. But the search of food items and restaurants are working.

When I click on the featured restaurant link (Arrow mark) on the home screen of the app it says FAILED:ERROR

II) After adding items to cart, when I try to click on the cart icon, the application says FAILED:ERROR and Make your first order. Your cart is empty…...

It shows a PLACE ORDER button. When I click on the Place Order button it says “PLEASE SELECT TRANSACTION TYPE”

What can be done?
