I was importing a backup made with phpmyadmin (latest version of zen cart)

It works but... it gave me 1 error message on 2 alters:

#1216 - Cannot add or update a child row: a foreign key constraint fails

It did not want to do the following 2 alters:

ALTER TABLE `eav_entity_attribute` ADD CONSTRAINT `FK_EAV_ENTITY_ATTRIBUTE_ATTRIBUTE` FOREIGN KEY ( `attribute_id` ) REFERENCES `eav_attribute` ( `attribute_id` ) ONDELETE CASCADE ON UPDATE CASCADE ,
ADD CONSTRAINT `FK_EAV_ENTITY_ATTRIBUTE_GROUP` FOREIGN KEY ( `attribute_group_id` ) REFERENCES `eav_attribute_group` ( `attribute_group_id` ) ON DELETE CASCADEON UPDATE CASCADE ;

I know that a while ago I changed the 2 creation statements of the table to add the constraints on that place.

Does anybody has seen this before?
