I reorganized some files and changed the location of a custom widget control. I went in and updated the path in the settings for this widget. The pages that contain the widget are still saying the resource cannot be found. I went in to edit one of these pages, and it shows an error along with the old path. Is it true that if you move a widget ASCX file and update the path, you have to re-add it to all of the pages that use it?
