I'm have customized my homepage in SharePoint Designer 2010.
I want to go back to a previous version, so I right click on the aspx file in sharepoint designer and choose "version history".
When I do that I get this message:
There was an error connecting to the server. The server error encountered is "Value cannot be null. Parameter name: key"
What should I do in order to revert my aspx page to a previous version ?
