In Sitecore 8.2 Update 3, when I try and rebuild an index from inside the content editor (From the Developer ribbon) when the dialog opens that should be a progress bar showing the rebuilding progress, instead I get a little desktop:

enter image description here

I dont see an error in the logs but I do see in the logs that the index rebuild is happening. If I close the dialog, I get the index rebuilt successfully confirmation dialog.


When I make the rebuild request, there are two outgoing requests. The second one is checking progress. The first one is maybe opening the dialog?


And this one check the progress

  • Open the chrome devs tools, in the navigation tab do you see the request going out for the iframe. What is the url its requesting and what is the response?

  • I don't have that specific version of Sitecore installed but this looks like a bug. I would raise support ticket to Sitecore Support Oct 23, 2018 at 18:27

OK. Found the problem. During a scan of the site I found a bunch of links like this:


So I built a redirect rule to strip those out:

  <rule name="Expanded Links" stopProcessing="true">
    <match url=".+?(?=~\/)" ignoreCase="true" />
      <action type="Redirect" redirectType="Permanent" logRewrittenUrl="true" url="{R:0}" appendQueryString="false" />

That rules breaks the dialog
