I migrated a site collection from one sharepoint 2013 server to another 2013 server.
After migration, I cannot open the nintex form designer. The error message is Invalid enum value "String 2" cannot be deserialized into type 'system.web.ui.webcontrols.validationdatatype'. How do I fix the problem.
It looks I can open the nintex form designer on other lists. The problem only occurs on one list. Can I delete the existing form and manually import it? Thanks.
I suggest you check the Nintex Forms setup.
Does any of this help opening the form designer?
