Source File: C:\CheckOut\VEPWeb\web.config Line: 88Check your References folder for missing a assembly, it should have a
warning icon.
It should be 'IBA.Common.Controls.WebControls.ScrollableGrid'.
Delete the reference then re-add it. If that still doesn't work re-compile
'IBA.Common.Controls.WebControls' solution and update the reference.
