To check this issue, open an elevated Sharepoint 2010 Management Shell and run the following:
(get-spserver $env:computername).NeedsUpgradeIf the the output says True, then you need to upgrade the Sharepoint database. To do that, open an elevated Command Prompt and run the following:
cd \"Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN"It should take about 5-10 minutes depending on hardware and the size of the database. It should say successfully upgraded database. I recommend rebooting the server afterwards just to be sure.
PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures
