Server Error - You need a more recent version of SharePoint Designer
- Posted by: Hayden Sinclair
An as Auckland, New Zealand based SharePoint Developer I have worked with SharePoint long enough to not be surprised when annoying error messages pop up. In this case...
Server error: The version of Microsoft SharePoint Foundation running on the server is more recent than the version of SharePoint Designer you are using. You need a more recent version of SharePoint Designer.
I haven't​ seen this error in a while, and I knew it had nothing to do with using the wrong version of SharePoint Designer, so I restarted my computer, logged into the site via Internet Explorer, opened SharePoint Designer and it went away.
Perhaps a restart is all you need as well? Give it a try.
