Quantity/stock problem after update to 1.6

[ietax]

After update to 1.6.1.1 i do not have quantity correct

 

I updated from 1.5.6.2 to 1.5.6.3 after 1.6.0.5 ecc.. last 1.6.1.1

 

 

 

 

some products in the db are at quantity 0 and in BO are at quantity>0

 

some productS in the DB are at quantity more than 0 and in BO they display only the character "-" (oldest products)

 thanks

Are/were you using any override or advanced stock management? You should check both the ps_product table and ps_stock_available, and see what they read for those products
