Does a wordpress mysql user need any priveleges other than
Wanting to make sure all DB users listed in wp-config have only access needed and not the entire kitchen sink.
At a bare minimum, you'll also need DELETE.
That being said, full privileges are recommended to make automatic upgrades and plugin installation work properly. Using a MySQL user with limited privileges is likely to cause weird issues, I'm afraid.
ah ok. one can dream i guess. thx
