I had a problem with a form not showing up last week. It seems that the form was set as "inactive" somehow but I don't understand where that setting is supposed to be toggled - if it exists.
At least according to the documentation, with the form function, it seems that one of the parameters references this:
gravity_form($formid, $display_title=true, $display_description=true, $display_inactive=false, $field_values=null, $ajax=false, $tabindex);
I am referencing the $display_inactive=false
portion...
