Magento 2.4.2-p1
Smartwave Porto theme
extensions from Amasty

I've manually duplicated our 2nd website because of problems we were having (as can be seen here: 'Unique constraint violation found' - when updating existing orders )

I have done the following:

  • set up a new website, store and store front
  • connected the new website to the existing categories (from the old 2nd website)
  • I've gone through the products and added them to the new website
  • I've added the new website/store/storefront to the appropriate CMS pages and blocks
  • I've added extension configuration to include the new website

Then I've done a test order and:

  • The great news is - I don't have the same problem with updating orders which I had on the old website (as referenced above)

  • there are, however, 2 problems:

    1. The websites do not share the same customer information (login info etc.)

    2. I get the following Error after submitting an Order:

    Invalid Form Key. Please refresh the page.

(the order is submitted but the Error comes up which will annoy customers)

How to resolve #1 and #2 above?

UPDATED on November 23rd, 2021:

What I want to do is the following:

I have these websites in the same Magento install:

  • website 0
  • website 1
  • website 2
  • website 3
  • website 4
  • website 5

I want to share customer information only between store 2 and 5. Would I be able to use this Export/re-import process?

-> System -> Data Transfer -> Export -> select website 2 in the 'Associated to Website' drop-down here:

enter image description here

Then Import this into website 5? Would this work?

I have tried the Customer Export and re-import as stated above but it does not appear to be working. Would anyone know why that might be? I have documented that in more detail here:

I have created an identical website/store (ID in database 8) to another existing website/store (website ID 2) and everything works except logging in

If you want to have single account for all multi-stores you have to do the following:

1 Share customer accounts

You can configure this feature here: System -> Configuration -> Customer Configuration -> Share Customer Accounts.

  • Thank you for that Gohil. I saw this was an option in the Admin panel. I was hoping to just share 2 websites (not all). If not possible, what would happen to accounts that had the same user name/password on 2 different websites? Does turning this on merge the already created accounts or does that only work going forward? There surely must be a way to only share the customer information between 2 websites in the same Magento install and leave 1 other website out of it?

  • Thank you trying to help. I decided to go through the route of Exporting customers from website/store 2 and re-import into website/store 8 but it doesn't work (does not log anyone in). Would you happen to know why and how to fix this? More details are here: magento.stackexchange.com/questions/350109/…
