Unable to use GRID VIEW in a report although no client side Deluge Script is configured in the form.

As title says, I'm unable to use GRID VIEW in a report although no client side Deluge Script is configured in the form. At least none that I can see. Anyone would know how to solve this or how to troubleshoot?
