I've been discussing this in another thread, but I thought I'd start a new one in case anyone else is having this problem and/or can help shed light. Here are the symptoms:
- Since installing the new beta and not before, I've been unable to access the Control Panels of any of my non-root blogs (meaning the blog at holisticnetworking.net is fine, but the blog at holisticnetworking.net/plugins is not accessible).
- I've checked the cookies and they are definitely getting set when I login from any login screen (root blog or otherwise). However, when I attempt to access the Control Panels of any of the sub blogs, I get the logon screen again. Logging in yields no error messages, sets cookies correctly if they aren't already, but still brings me right back to the logon screen. This does not, therefore, appear to be an authentication issue.
- I've discovered this thread, which says that redirecting domain.com to http://www.domain.com yields the same behaviour. However, I'm confused why this didn't pose a problem with any previous version of WPMU and is suddenly a problem with this new version. What changed?
Thanks to anyone who can help. It should be noted that I've completely deleted everything off the server, save for the database, and installed the latest version in Trak as of last night. This has not resolved the issue.
