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?
Migrate sharepoint from the testing site to the production site. However the two environments are running the different versions of Nintex. The testing site is 188.8.131.52 whereas the production is 184.108.40.206
The form on all subsites can be opened fine in the designer. I suspect the form on the parent site is corrupted. But I am not able to delete it, because I cannot access the deletion button in the ribbon. The nintex form affect the form designer.
