"Could not find valid key" when users register with drupal

[strangefeatures]

Hi,

I've just been reading the post over at http://forum.civicrm.org/index.php/topic,114.msg403/topicseen.html, as I'm having a similar problem to what occurred there - when anonymous users sign up for a new account, this error message is displayed:

Code: [Select]

unrecoverable error
    Sorry. A non-recoverable error has occurred.

    Could not find valid Key CRM_Core_Controller_Simple

    Return to home page.

I'm running CiviCRM 2.0.4 and drupal 5.7
but none of the suggested remedies are working. Specifically, I have:

   1. cleared drupal's cache table
   2. turned off drupal caching ( I think - it's still populating the cache table but shouldn't be using it)
   3. set the base_url in settings.php
   4. made sure the URL in civicrm.settings.php matches that base_url
   5. truncated the drupal sessions table
   6. cleared browser cookies

Update: on the basis of the advice over at http://issues.civicrm.org/jira/browse/CRM-1948, I also checked that the drupal anonymous user (uid 0) was present. It wasn't, so I added that in with:

Code: [Select]

INSERT INTO users (uid,name,mail) VALUES(0,'','') but the problem still persists.

Is anyone able to provide me with any other ideas?

[strangefeatures]

No, no - ignore me.

It looks like inserting the uid 0 entry into the drupal users table did do the trick - I think I might have forgotten to truncate the sessions table after doing that.

Thank you very much man, I had the same issue, I deleted user@uid=0 and found your post.
