I've been a WordPress user for years and have never encountered this particular problem. When I try to login using the proper password, I get the error message "Your session has expired."
I've cleared my cache, my cookies, etc. I've restarted my browser several times. Didn't help.
Then, of course, I searched the forums, and I found and tried this fix, and changed my password two separate times:
"Try this. I've done this before on 2.1.3 and it seemed to work just fine.
Go to your WordPress Database.
Select "wp_users" (It could be what ever you specified in the installation of the DB prefix)
Select your username and select "Edit"
You'll see a line of MD5 in the "user_pass" field. Delete it.
Enter the new password and from the dropdown box select "MD5" (You MUST do that or it wont work)
Now try to login with the password you typed in. -NOT the long bit of MD5 you see-
All should be well."
Unfortunately, all is not well. I continue to receive the error message every time I type in the correct password. Also, my user name is replaced by a string of numbers.
When I type in the wrong password, I get "Incorrect password."
I'd appreciate any help you are able to offer.
