Two Users with same license, profile and permission sets. One gets error on "load more". Salesforce

Raymond, can you post the code for the VF Override page that is used to display Skuid?

Is this happening when you “Preview” the Skuid page from Page Composer as well as when using Skuid from a VF override page?

Can you post the XML for just the Models in the Skuid Page? That might help narrow down.
