I have an issue that I have never seen before. We have a sharepoint site on Foundation 2010 that was upgraded from a 2007 site. Several of the old forms do not show up in designer, so we cannot edit them. the forms are there and functioning, but we cannot edit or remove them. I have tried creating a new form with the same name, but it will not allow me to upload it because the form already exists. I need to edit 1 of these forms,
Any ideas on how I can remove the existing form from the site even though it does not show up in designer?
