cant remove products

I can not remove products i get this message:

Could not clear category products
Product Category could not be deleted.

Are you sure you are deleting product , the message informs you that you can not delete category???

product category sorry about that

vmError: Could not clear category products
Product Category could not be deleted.

You must delete all products from the category first. Then you can delete the category itself.

There are no products

Do you have anything else connected to that category, like some other component or so???

for example if you have additional component it could create relation table between vm category table and it's table so database prohibits deletion because there some field is foreign field belonging to vm categories table.
