I have no paging option specified and I'm getting this error.

Going back to the old version solves the issue.

Here's the definition

$(this).igGrid({

            primaryKey: "ID",

            autoCommit: true,

            autoGenerateColumns: false,

            columns: columns,

            showFooter: true,

            renderCheckboxes: true,            

            enableUTCDates: true,

            features: features,

            odata: true,

            responseContentType: "application/json",

            responseDataKey: "results",

            virtualization: "false"

        });

Features are grouping on with one column grouped, sorting = multi (local) and 2 summaries in the footer. (standard, no custom), resizing is on, as is allow hiding and selection = row. No editing.
