Error Message

Hi,
I installed Open Pushish http://openpublishapp.com and I'm testing this Drupal Tailored Distro.

I tried to create my first Topin Hub, but when I add Condition 1 (Topic -> Business -> Condition 1) and after I save I get a Blank Page with this error message:

Fatal error: Class name must be a valid object or a string in /home/~/openpublish/sites/all/modules/ctools/includes/export.inc on line 905

I don't know happen it.

What I have to change to correct this problem?
Can you help me please?

Best regards

Var och hur tar man kontroll över vilka meddelanden som visas?
I min modul sätter jag ett meddelande med drupal_set_messages och med en egen typ vid en validering.

Jag vill kunna välja vilken typ av meddelanden som visas, exv ta bort en typ för en viss roll.

Har kikat på theme_status_messages(), men får inte grepp om hur det används.
Har någon nått tips?

My site reports section show top pages as " /admin/reports/request-test". What page is this? I checked the page by clicking on it and it shows nothing but "request test" on a white background.

I have found following error messages in my server log.
