Portal Page not works in production environment

The problem is cache. Added context.no_cache = 1. Thanks to @treeem for the solution mentioned in Frappe context not changing. Cache problem

I changed the .py to

import frappe
from frappe.utils.data import ceil

def get_context(context):
     **********
     **********

     context.no_cache = 1

     return context
