I can edit everything on the homepage except the Contact Us form. It is not a gravity form listed in our list of forms, and it is not a contact form 7 plug in. It is not a sidebar. I cannot get to it in Widgets or any other area. I need help because there is an error on the form and I cannot edit it.
That contact form is in a widget. Look at the widgets (in Admin area, Themes) to find that widget. (You can tell by inspecting the code for that area, and seeing that the form is contained within a div with a class of 'widget-area', among other classes.)
It's possible that the contact form code is wholly contained in the widget.
