Hi everyone,
Im in the same boat as @agemo i get exactly the same error and I’m handy with fiddling with database directly.
Here is what I do not understand. The suggested solution is to simply delete the pools of duplicate id in value column, but when I checked my table it turns out those duplicate entries all have reference to different post_id so belong to different posts and also have different meta such as amount of votes and etc
Can someone explain to me old structure vs new structure so I can understand this error. To me deleting polls does not solve the problem as I actually delete users data.
Thank you!
