Did you read the reply I linked to on your last topic?

I believe this is because of DB differences between phpBB 3.0x and 3.1x.

Current import only supports phpBB 3.0x

I was able to get rid of the error messages by creating the columns it complains about.

You can also try this: https://bbpress.trac.wordpress.org/attachment/ticket/2716/2716.1.diff

If you did try the patch and it did not work, I can contact the devs for that because some other user had an issue also.
