In older versions you have to manual change the field length in a couple of tables ...
Are you able to upgrade?
If not, in v1.3.x we changed the table fields to:
PHP Code:
ALTER TABLE customers_basket_attributes CHANGE products_options_value_text products_options_value_text BLOB NULL DEFAULT NULL;
ALTER TABLE orders_products_attributes CHANGE products_options_values products_options_values BLOB NOT NULL;
NOTE: This would have to be tested to assure that this is enough of a change in your version ... I am pretty sure that is all you will need ... I think ...
