You may receive this error when trying to publish a page in SharePoint 2010

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.

Solution:
You would need to install the ‘State Service’ via the Configuration wizard in Central Administration or via PowerShell.

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)

Tip:

You can view a list of all State Service cmdlets in Windows PowerShell by typing gcm *spstate*
