Problem: “Your server may be of higher version than the currently installed SharePoint Designer”
I recently faced a problem, where I was prompted to login again & again in the SharePoint claims website. I was working in a farm environment with 1 WFE, 1 application server & 1 DB server.
When I open SharePoint designer & try to connect to the website. I was authenticated but again redirected to login page & continuously it happens. SharePoint Designer 2010 gives an error message somewhat like “Your server may be of higher version than the currently installed SharePoint Designer”.
Solution was so simple. You can go to central admin. Under Manage servers in this farm, you could see that one or more servers needs upgrade. So, to solve this problem, you could just logon to those servers & run configuration wizard, which would solve the problem.
Note: You may need to do IIS reset on other servers.
Hope it helps! Enjoy SharePoint 🙂
