v8.1.2 Page Editor ERROR - A serious error occurred please contact the administrator

Ok so, I've upgraded to v8.1.2 with a scenario based off disabling analytics and simply the CMS-only mode. Not sure if in the process a Experience Platform config setting is supposed to be enabled or not BUT I following the instructions to a "T". This version is functioning well but have just run into this page editor error. I page publish>preview and it displays this error..

"A serious error occurred please contact the administrator"

Please advise,

Thx

  • this worked for me... For now I just reverted to SheerUI and disable "RibbonPageExtender"

    Sitecore.ExperienceEditor.Config

    <pageextenders>
    <!-- Uncomment the page extenders below and comment the "Sitecore.ExperienceEditor.Speak.Ribbon.PageExtender.RibbonPageExtender" to switch to old SheerUI-based Experience Editor ribbon. -->
    <pageextender type="Sitecore.Layouts.PageExtenders.PreviewPageExtender, Sitecore.ExperienceEditor" />
    <pageextender type="Sitecore.Layouts.PageExtenders.WebEditPageExtender, Sitecore.ExperienceEditor" />
    <pageextender type="Sitecore.Layouts.PageExtenders.DebuggerPageExtender, Sitecore.ExperienceEditor" />

    <pageextender type="Sitecore.Shell.Applications.Preview.SimulatedDevicePreview.PageExtenders.PreviewExtender, Sitecore.ExperienceEditor" />

    <!-- Page extender for SPEAK-based Experience Editor ribbon.
    <pageextender type="Sitecore.ExperienceEditor.Speak.Ribbon.PageExtender.RibbonPageExtender, Sitecore.ExperienceEditor.Speak.Ribbon" />-->
    </pageextenders>
