Nop 3.6 to 3.9 upgrade

I have upgraded using upgrade scripts Nop 3.6 to 3.9 but there were two problems.
1) Table for Store pickup point was missing.
2) Shipping.FixedOrByWeight plugin not working.

First one i have solved by creating the table using the following script in SQL

USE [DATABASE NAME]
GO

/****** Object:  Table [dbo].[StorePickupPoint]    Script Date: 4/25/2017 4:07:54 PM ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[StorePickupPoint](
  [Id] [int] IDENTITY(1,1) NOT NULL,
  [Name] [nvarchar](max) NULL,
  [Description] [nvarchar](max) NULL,
  [AddressId] [int] NOT NULL,
  [PickupFee] [decimal](18, 4) NOT NULL,
  [OpeningHours] [nvarchar](max) NULL,
  [StoreId] [int] NOT NULL,
PRIMARY KEY CLUSTERED
(
  [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

GO


Plz help me with the second one.

Thanks in Advance

RE: "Shipping.FixedOrByWeight plugin not working."

Would you be more specific?  

See if this post helps.

HI,

My problem is different from as specified in the link provided.
Actually am getting an error message " Shipping options could not be loaded'.

It means the plugin is not calculating the shipping charges.

Thanks
