In my Default Display form I had previous added a webpart which included javascript code to suppress some of the form fields - all good so far.
Today, I wanted to add a webpart to display a list view, after I added the list view web part I got an error on the page, I then clicked stopped editing.
Problem: when I went back to edit the Default Display Form, I am presented with blank/white space in the area of the page where previously the editable form would appear. The screen still displays the top ribbon, left-side navigation menu, just no form which I can edit.
Preference #1 - is there a way to roll back to the previous version of the form?
Preference #2 - is it possible to edit the DispForm.aspx file to remove the list and javascript webparts
Preference #3 - how can I reload/reset the display form back to factory default?
Note: I do not have access to InfoPath nor SharePoint Designer.
