Like an excited child at Christmas I've downloaded and installed the latest release of Nintex 2016 to my dev box. Gone to a custom list, clicked on the Nintex Forms button in the ribbon and...
....nothing! The button is unresponsive (pun intended).
I can click the down arrow to customise my item form but when I click that, nothing. The form designer will not load.
It was working fine before.
In Nintex Administration If I click on the "Form designer experience" link or the "Responsive forms template" link, I get a "Sorry, something went wrong" error.
Could not load type 'Nintex.Forms.SharePoint.AdministrationPages.DesignerExperience'.
The other pages in admin appear to work fine.
There was no error during the install process.
In the logs, the only errors are similar to the error given on the screen around not being able to load the type.
I've checked the Web Application Features, the Site Collection features and Site features. All are active. I would try reactivating them but the fact that the admin pages don't load suggest there's another issue.
Hmmm I would try that on my dev machine too but regarding your feedback I'm gonna wait until it's working for you
However, did you see if all farm solutions are deployed without any error message in central administration? For me it sounds like deploying a solution didn't work properly and an assembly is missing. Even if CA says everything is deployed correctly, just re-deploy all of the required nintex WSPs. And please do it via PowerShell NOT via CA!
