When I save and publish a Nintex Form on a custom list in SharePoint 2013, it will update the "New Item" in the Ribbon to the form's URL, but not the "new item" in the list:
In this particular form, there was an InfoPath form, which I got rid of via the Form Settings in List Properties, including deleting it from the server. If I click on the "new item", I get a 404 error, which makes me think it's looking for the deleted Infopath form. Am I missing something, or is this a bug in publishing Nintex Forms?
It turned out that if I "Show Toolbar" in the Toolbar Type in the "Edit Web Part" menu, this problem disappeared.
