#183 AttributeError when trying to view existing content panel

[Nate Aune]

I'm trying to use CMFContentPanels 1.7a and when I try to view a
content panel which I created with 1.6, it gives the following error:

Traceback (innermost last):

Clarification: the error does not occur when I try to view the item (it
shows only the title and description, but none of the content panels show
up), but when I click on the "Config" tab.

you must reinstall CMFContentPanels.
