Error Duplicate entry for key 'uk_ecm_files'

Hello

this error appeared after upgrade from 13 to 14.0.5

Error Duplicate entry for key ‘uk_ecm_files’

when I go to this link

user/card.php?id=2

any idea ?

I use to get this message when my pictures for a product were restored between upgrades / migrations. I ignored - I only got an alert, not a full page error.

This error only happened once per product for me. So if there is no loss of data or associated files to the user card… see if you keep getting the same error for the same card.
