Hi Mike,
I’m sorry that this is taking so long but I think I see the issue now. Can you please run one more query for me to verify the superfluous primary key on the exp_weblog_data table (we’ll deal with one table at a time)?
show create table exp_weblog_dataSo, you can run altering DB queries on the dev server without fear and can rollback to the working DB if required?
Cheers
Greg
