I'm encountering this error in all of my site collections where i had published the Nintex forms. If I edit the form of any list with Nintex, the Default Display and Edit forms are no longer available and they show error.
Something like this in ULS logs:
|Medium||MetadataNavigationContext Page_InitComplete: No XsltListViewWebPart was found on this page. Hiding key filters and downgrading tree functionality to legacy ListViewWebPart(v3) level for this list.|
The form opens fine with SharePoint designer. If I remove the Nintex form from the list, the Display and Edit forms work again. This is strange because i'm realizing this for the first time. Has anyone encountered it?
I'm working with SP2010, NF2010 ver 220.127.116.11
