Skuid/Nintex Friends,

We’re upgrading from skuid 10.0.27 (I know!) to 15.3.26.

In our existing production environment we have a force.com site with a guest user using stored credentials on a salesforce “external” data source. Using this method to connect back to the same instance of salesforce that the pages are running on, allowing the guest user to edit records and upload files. It’s working great in 10.0, but in our dev-ed where we upgraded to 15.3.26, we’re getting errors.

“Insufficient access rights on cross-reference id: [a salesforce id]”
It seems like the guest user cannot edit an existing record.

I imagine I’m missing some settings somewhere… and ideas?

As far as I can tell the guest user permissions, sharing rules, and the data source are all set up identically in both environments.
