ISSUEWhen trying to access the management links in Central Administration, the following error might occur:
The expression prefix 'NFResources' was not recognized. Please correct the prefix or register the prefix in the section of configuration.
- Navigate to: Central Administration > Application Management > Manage web applications
- Select the Web application you're using for Nintex Forms.
- Click on Manage Features from the ribbon.
- Deactivate (if active).
- Re-activate the "Nintex Forms 2010(2013)" feature.
Note: This will trigger a web.config update that will recycle the application pool (something to be aware of if this is on your production environment).
