I made some modifications in a page a using SPDesigner 2013. When I try to open the page I get an error, so I want to revert back to a previous version. When I try to go back to a previous version in SharePoint Designer, however, I get the error:
Versions cannot be accessed at this time because server is busy .Please try again later.
How can I fix this and/or access my version history to restore a previous version of my page?
