I am using SharePoint 2016 On Premises. I am currently unable to use SharePoint Designer to create any custom form (NewForm, EditForm, DispForm). If I try I get the following error (Could not Save the list changes to the server). That is the only error I get, nothing in the SharePoint logs. I have read that this has been removed from SharePoint Online but I am using SharePoint On Premises. Is it possible that this removal has affected my on premise setup? If so how do I get it back? Thanks.
Are there lookup columns in the list? Have you made any changes to the SharePoint server recently(upgrade/update)?
