Object reference not set to an instance of an object - Old List Form Web part

[tony_jose]

Hi,

I have updated Nintex Form from version 2.3.31 to 2.11.5 directly.  Now I am getting an error when opening a registration page with NintexForm, "Object reference not set to an instance of an object." 

When I remove and added List Form web part back on the page, it started function as expected.  My problem is that I have more than 50 web pages to be replaced.  So I think the old ListForm webpart is nomore functioning as it should.   Is there alternative way to update the oldwebpart so that I can avoid manual replace process.

Thanks

Tony
