I got caught unaware with a new update to a new version of MWiki, in which my old password was rendered unusable. This is a local installation with no internet access to any outside my computer, so I have not been "hacked." The account is still there, I simply cannot:
1) log in, won't accept stored password;
2) cannot CHANGE pw because of the above; will not accept "previous" password. I don't really want to set up another account; I want to use the one I already have.
So, how to nuke the existing password and account files, and simply set up a new account over the old one? Surely there's a way to do that.
