Error on import Acymailing Subscriber
The only reason I can think of now is Primary key ( ID in most cases ) value is different on both the sites, that's why It's trying to update a different record. Please check if the email ID is having same Primary key value on both the domains.
With the error message, It's quite evident that your are trying to add a subscriber which is already there in Database. Please clarify the issue a bit more in detail if I'm missing something here.
I try to import Acymailing subscriber but it failes.
I got this message :
Import abort with exception
I try the importation, without email, but i get the same message.
Thanks for your help
