I have a hybrid server that is running 7 wordpress blogs. I suddenly can't login to any of them. The login page doesn't shake like when the password is wrong, it just reloads. I have been working on this for over 24 hours and am at my wits end.
I have been through all of the steps on this page with no success:
I have uploaded a fresh copy of wordpress over my existing installation.
Also, the reset password function does not work. It gives me the error:enter a username or email address. I double checked my email address in phpmyadmin and I am using the correct one. I also tried registering a new user and it tells me "please enter a username and please type your email address."
It seems to me that the data is not getting submitted, but I am not sure.
I have read through many posts regarding this problem, but none of the solutions seem to help.
