CiviCRM Community Forums (archive)

I have a "no valid key for session" error when I use a Petition. Only for anonymous users, and they get it when submitting the petition. It does not matter if they have filled it in correctly or if they have left required fields open: after submitting you get the error.

It's an older civicrm that I upgraded.
The version used to be 3.4.1 and I upgraded to 4.3.4 (drupal 6).

The older civicrm also had this error and the new one too.

It's drupal6 and the language is Dutch.

The following is what I get in the logging:

I tried it on demo.civicrm.org, I tried another civicrm with drupal 6 with Dutch language. No other instance I can find has this particular problem.
Off course I deleted all caches and Config.IDS.ini (several times).

Please help me find the cause.

Oh my...
Why do I do that: taking over sites from others.

I have solved the issue.
I hope no-one will ever encounter something like this, but if it happens somewhere ever again, I hope that person finds this thread.

In this case some id**t had deleted uid 0 from the drupal users table...
And then the session (with the qfKey) is not properly stored and/or retrieved, making civicrm form submissions invalid for anonymous users.

So the solution: Add record with uid 0 to drupal users table and it is solved.

Ah, thanks..

That actually makes sense.

The builders of the site have made choices I would never make (that always happens), but have not made mistakes like this and I know the site has been moved from one host to another.

Good that this is in the forum now, other people DO have a chance to run into it then.
