Weird. I just added a description to the category and it seems to have fixed the error.
However, the category still has 436 products in it on the frontend and none in the backend. Any ideas?
I also just noticed that I’m getting the following error when I try to make any changes to the products in that category:
SQLSTATE: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`nirvanadb/catalog_category_product_index`, CONSTRAINT `FK_CATALOG_CATEGORY_PRODUCT_INDEX_CATEGORY_ENTITY` FOREIGN KEY (`category_id`) REFERENCES `catalog_category_entity` (`entity_id`) O)
