Column count doesn't match on saving the product after magneto upgrade
SQLSTATE[21S01]: Insert value list does not match column list: 1136 Column count doesn't match value count at row 1. This problem was with the 9th column in catalogrule_product_price. It seems TBT adds a 9th column called rules_hash. It seems the newer versions don’t need this. You can looked at a magento 188.8.131.52 database and sure enough the stock database table doesn’t have this column. You can drop the field "rules_hash" and now no more error.
