The form cannot be rendered. This may be due to a misconfiguration of the Microsoft SharePoint Server State Service. For more information, contact your server administrator.Problem:
The State Service is not configured. When you decide to configure everything yourself when installing 2010, the state service can only be installed/configured using PowerShell or the configuration wizard.
Configure via configuration wizard:
Go to central admin, click on Configuration Wizards, Launch the Farm Configuration Wizard. Check the box for State Service and deselect everything else. Click on Next.
You can install it with Powershell, which I didn't choose. I was reading that it can be problematic. At some point I will research again and maybe the bugs will be worked out.
To configure the State Service by using Windows PowerShell:
1. Click Start, Administrative Tools, Windows PowerShell Modules.
2. In Windows PowerShell, type $serviceApp = New-SPStateServiceApplication -Name “State Service”3. Create a State Service database and associate it with a service application, by typing New-SPStateServiceDatabase -Name “StateServiceDatabase” -ServiceApplication $serviceApp
4. Create a State Service Application Proxy and associate it with the service application by typing New-SPStateServiceApplicationProxy -Name “State Service” -ServiceApplication $serviceApp -DefaultProxyGroup
(You can use another proxy group if necessary by changing the DefaultProxyGroup parameter)
