Have you resolved this yet? I am having the same problem and have tried all of these things too. I have notice that after I try to login to WP, the MD5 pw stored in mySQL gets changed to something different from what the value I used when I reset it thru the command prompt (and yes, I did verify that my change was correctly applied).
Please Help!
I am having the same problem – Did you find a solution?
WP blog page displays OK, login page displays OK, but when I attempt to log-in with admin, the login screen refreshes but otherwise nothing seems to happen. However, when I look in the DB, it “looks” like the password is somehow being reset by something because it is different from the MD5 value that had previously been there.
I have event reset the admin password in mySQL with a newly generated MD5 password. After I update the password in mySQL, I check to see that it “took”. Then I try to log in again. I just get the login screen refreshed (and no error messages). But when I check the password in mySQL again, it is a different from what it was the last time even though I didn’t reset it.
