login issues

I cannot login to keeps saying Unknown user or incorrect password, i have gone the forgot password route severally but it wont log me in even after changing password.
Anyone experiencing same issues?

I’ve read that sometimes it can take up to 24 hours for password change to take effect.

I think its something to do with the most recent upgrade, I didnt forget the password in the first place, I tried logging in but it wont let me before opting to change password
