Update: Fixed! It was an issue with changes to the way the web host was handling domain forwarding.
A client who has an old Drupal 5 site all of a sudden found they can't log in. I've tried to login as user1 and get an access denied message, although it seems to be recognizing me as user 1.
I can't find any session cookies for the domain on my browser, although the response headers show a session cookie being set. I suspect this is where the problem lies, although I'm not sure where to go from here. I've emptied the sessions table and cache and nothing happens.
I see a message on my client's hosting control panel that says Suhosin is now enabled… I see from some discussions here that this can have an effect on cookies.
If anyone has experienced and solved an issue like this I'd love to hear how you did it, because at this point my brain hurts from thinking about this. :)
Thanks!
