cannot login

When I attempt to login to Modx I get sent back to the login screen. No errors of any kind. I've checked the database and modx_session shows a new session. As well, modx_user_attributes increments my login count, suggesting to me that I have been authenticated. I've changed the password via phpMyAdmin and I've tried different different browsers. I've truncated modx_session and I've cleared browser cookies. This isn't a fresh install and I have been able to login before.

The behavior of the issue is similar to what has been described here:http://tracker.modx.com/issues/6465

The version I'm using is MODX Revolution 2.2.14-pl.

Any ideas as to what might cause this?

Thanks!

How did you change the password via phpMyAdmin?

UPDATE modx_users SET hash_class = 'hashing.modMD5', password = MD5('the-new-password') WHERE username = 'theusername';

as per this file http://rtfm.modx.com/revolution/2.x/administering-your-site/security/troubleshooting-security/resetting-a-user-password-manually

Have you tried manually deleting all files in the core/cache directory?

And make sure to clear your browser cache and cookies for the domain as well.

Another possibility, which I would hope has not happened, is that your site has been hacked and your user disable or set to inactive. That version of MODX is subject to hacks that allow the creation of arbitrary users.

You might take a quick look at the modx_users table in PhpMyAdmin to see if there are any unexpected users there.
