Can't log in to manager: There was an error retrieving or creating session id

I am locked out of my manager. I keep getting this error:


I am using ssl and I think this may have something to do with it. I am redirecting my entire site through https. Although upon removing all rewrites in my .htaccess file this error still remains. So I have no idea where it is coming from. I have tried setting session_cookie_secure to 1 and session_cookie_httponly to 0 as mentioned here: http://forums.modx.com/thread/73901/can-t-log-in-to-the-manager-of-a-copied-modx-site

Has anyone seen this error before? What does it normally suggest?

EDIT:
I've tried all different system settings. Here are my settings currently that I think might be related:
server_protocol https
session_cookie_domain
session_cookie_lifetime 604800
session_cookie_path
session_cookie_secure 1

Again, I'm redirecting all requests to my site through https using .htaccess file. Sometimes I can log into my manager after many refreshes and login attempts but the dashboard is just the menu bar and a white screen. None of the links work either. I've also noticed that the session table in the database creates a new entry on every page visit! What is causing this?? [ed. note: csauer last edited this post 10 years, 11 months ago.]

Can anyone help with this?

I found this forum post: http://forums.modx.com/thread/83244/encrypted-session-data-with-suhosin

I found the setting in my database for 'session_handler_class' and have changed it to be a blank value. This worked for a little while but a few days later I came back to my manager and the same error was present again.


Is this just a workaround? Does anyone have an idea of an underlying cause? That post said that changing 'session_handler_class' to a blank value will use the servers default session handler. Could my server not be configured correctly? I am using Bluehost as my hosting provider.
