View State Error when user tries to check in file RRS feed

  • Question

  • Recently we encounter issue with SharePoint 2007 that the user is unable to check in file. Whenever user try to check in file, it will show error page: 


    Invalid viewstate.

    Any idea?? Thank you.

  • Apparently, changing the enableviewstatemac="false" solves the issue, but this is just temporary workaround. Anyone knows what might be wrong the viewstate with enableviewstatemac="true"?
