0 SQL= on Frontend of a list

[abel408]

I'm receiving this error when I try to view or create a record on a list on the frontend.

The requested page cannot be found.

0 SQL=​

I can view and add records from the backend but not the frontend. I have 2 lists. One works fine and one does not.

Any help is much appreciated. Thanks!
