If you delete a user-defined field that has been associated to a table of data the grid will give an error when you try to access it. You can fix this by editing the User-Defined field definition as follows: - Go to Administration > User-defined Fields - At the top right of the screen, click 'Manage' - In the pop up find the table of data on which you had the issue - Select it and click 'Edit' - Edit and or change the Sections and Fields - Click 'OK' The grid should now load as expected.
