and in looking at v201, this error seems to me to be a data issue. see this section of code.

to me, it seems that your table product_types is missing some data. the products in category 70 have a product type that are missing from that table.

as to whether the changes in v210 would account for this sort of data corruption, i can not say (ok, i probably could say, but i am not going to spend any time looking it up right now).

so i would examine that data for any missing records. it seems that creating any missing records is something that needs to be done in mysql, as the admin function does not provide for it.

see:

best.
Thanks Carl. I THINK I know what the problem is. It appears to be an import error from my csv file using DBIO. I think I accidentally created "music products". Looking further. This could be a bit of a mess. I have no music in my store at all.
