Pods Embed Error: ORDER BY contains SQL that is not allowed.

Hi,

I am trying to create a random list of pods elements. The list is called via the pods element listing widget. The widget works fine, if I leave the field “order by” blank. But as soon as I add “rand()” to this field, the frontend will display: Pods Embed Error: ORDER BY contains SQL that is not allowed.

Same result, if I call the list via a shortcode.

I have done this successfully on another website, but I don’t understand why it wouldn’t work now. Can you help?

Thanks,

Astrid
