Actually what started it was I was updating another site and put in the PW an Username for another site. So I went back and corrected it - on the updated site - but then these errors started to occur from which I got the wrong PW and username. I tried to run some SQL commands but they didn't do any good.
I can''t fully follow you, sorry. Can you please be a bit more detailed? It will help us in figuring out what might have caused the issue.
One word of advice if I may, don''t just run queries at the db, if you don''t know what you are doing, that is. It will make matters worse.
