To day I have got the problem when I am publishing the content and documents to internet web site in SharePoint. The error description is
“The form can not be rendered. This may be due to a misconfiguration of the Microsoft SharePoint Server state service”
The state service is automatically configured as part of the basic installation of SharePoint 2010. Advance installation requires the separate configuration of state service. Configuring the State Service after installation of SharePoint 2010 by using Power Shell or Farm configuration wizard
The solution to fix this error is well explained in both Power Shell and using the configuration wizard.
