product urls change to catalog/product/view/id/…

Hi Mikko,

Any info how to fix this? 

You can do the following steps so that M2 can re-generate URL rewrites for categories and associated products:

1 -- In categories management, create a new root category named ‘Temp Root Category’
2 -- Open Stores management, edit the default Store of the default Website and set the ‘Root Category’ form field to the newly added root category ‘Temp Root Category’ and click Save button.
3 -- Once done, open Stores management once again, edit the default Store of the default Website and set the Root Category form field to the main root category which you want to publish in the storefront again and click Save button.

Magento will re-generate categories and associated products URLs rewrite in this step. It might take sometime to complete this task (It depends on the volume of categories and associated products)

Once done, re-index the data and clean the Magento cache. And let me how it goes then.

Mall
