Re: Member’s ID issue after conversion
Well, you’d have to go poking around with phpMyAdmin, and change the users table and the usermeta table to match. This will prove difficult because the information is serialized in such a way as to make it difficult to read with the naked eye.
Will it cause a problem? In my OCD opinion, anything that isn’t meant to be that way can pose a problem later. How many users are affected by this issue? Can you delete them, reset the last ID in that table using phpMyAdmin, and ask them to re-register?
