    They are being caused by our site monitoring software...

    Why would Sitefinity do that?

    Hello Alfred Pena,

    We are not sure why the 3rd party software is causing the problem. How is it configured? Is Sitefinity running as a child application?

    Sorry this is not only happening with the website monitoring software it is also happening with users.

    The 3rd party software is just checks if the site is up...

    Hello Alfred Pena,

    It seems this specific error is caused by the SiteTreeView control, located in UserControls\Nav\SiteTreeview. Can you please check this control, if it is a custom one or it is the default one with some modifications? We see such for the first time, so I guess it is something custom in the code. You can send it to us so we can test it here.

    Best wishes,
