I am trying to see certain elements associated with an element. I do this on the client’s content management server. When I click Navigation → Links, nothing happens. I get this error in the JavaScript console:
http: //sitename.local/sitecore/shell/default.aspx? xmlcontrol = Gallery.Links & ... de-DE & vs = 1 & db = master & sc_content = master & ShowEditor = 1 & Ribbon.RenderTabs = true
Failed to load the resource: the server responded with a status of 500 (Internal server error)
Here is what I see in Sitecore logs:
