Plone site - AttributeError after buildout

Hi,

After updating buildout to try to resolve an editor issue, I ran "bin/builout -v" instead of "bin/buildout -Nv", which then updated a lot of my site's Products (my mistake for not pinning the versions). After completion, I'm able to start the instance (bin/instance fg), but when trying to access the site, I get:

Site Error
An error was encountered while publishing this resource.

AttributeError

(Also, the following error occurred while attempting to render the
standard error message, please see the event log for full details:

AttributeError: (see above)

I've tried rebuilding the catalog and flushing the cache, but I'm not sure what else I can do to get this back up and running. I can get to the ZMI, but none of the TTW pages.

Any ideas? I've been looking through Google and the old WF forums, but can't find an answer.

Thanks,
