Hi!
I've just installed this contribution and I'm getting this error when I push the update button in admin:
1062 - Duplicate entry '0-0' for key 1
insert into products_to_categories (products_id, categories_id) values ('0', '0')
[TEP STOP]
do you know how to solve this problem?
I've seen other people that have "1062 - Duplicate entry '1' for key 1" ....but it seems like it's not the same problem?
