I have asked this question in a previously and it was resolved by going back versions to find out the issue regarding my problem of blank preview for my form.
However, I have come back to my form and it is showing blank again. I have not made any alterations to it since and my last save was successful along with the preview. I can see this is the updated form as it has a new set of choices that I put in.
I am not sure what has happened. I therefore decided to press F12 when previewing the form and there are lots of errors in the debug facility.
Here are some of them -
SCRIPT1002: Syntax error
File: PreviewNintexForm.aspx, Line: 266, Column: 168
HTML1114: Codepage unicode from (UNICODE byte order mark) overrides conflicting codepage windows-1252 from (13)
SCRIPT1004: Expected ';'
File: PreviewNintexForm.aspx, Line: 1304, Column: 4294925867
SCRIPT1028: Expected identifier, string or number
File: ItemPicker.js, Line: 15, Column: 5
1028: Expected identifier, string or number
File: PreviewNintexForm.aspx, Line: 3523, Column: 267
I noted the undefined rules error which I thought I had dealt with by removing it when I saved over it with the new version?
if anyone is able to help I would very much appreciate it!
