Installing HTML5 Viewer from Post Install Results in Blank Page

Ethan Granger

I'm running GCE 4.2.2 and SLV 2.3.3. I just installed HTML5 Viewer 2.3.3 from the post installer (deployed management pack and registered with IIS there too). I've installed it to wwwroot\h5v folder, otherwise it is the default install. Browsing to http://server.domain.com/h5v/ loads the default world cities app.

When i add the HTML5 viewer to my site, however, all I get is the splash screen for 2 seconds and then the screen is compeletely blank. Nothing seems to load.

I can hardcode the uri into the wwwroot\h5v\Resources\config\Default\Desktop.json.js file, but that doesn't make any sense, especially if I have multiple apps. 

What am I doing wrong?

Thanks in advance.

    Hi,

    You can use the http redirect from IIS and add the path to the

    I'm getting the same issue.

    I have done a new installation of Geocortex Essentials, installed the HTML5 Viewer then created a new site with an HTML5 Viewer.  It displays the splash screen then displays a blank screen and hangs.  No errors are reported.  Fiddler displays an HTTP error 500, but how do I figure out what's going wrong?

    Hi, we just installed Essentials, and had the same problem with HTML5 viewer. Has anyone resolved this issue? Please help.

    Thanks.

    I am having the same issue as well. I think I'll be putting in a help ticket this afternoon and will post the results.

    Thanks.

    Hi Michael,

    If .Net was installed prior to IIS you may need to re-register .Net by executing the following command from an elevated command prompt window -

    aspnet_regiis -i

    you would first need to navigate to the following folder after launching the command window - 

    C:\Windows\Microsoft.NET\Framework64\v4.0.30319

    The symptom for this issue would be a 500.21 error.

    It's also possible it may be caused by missing "Application Development" roles in IIS.  I would try re-registering .Net first though.

    Thanks to Latitude support I've found the cause of my problem.

    The web.config in the C:\Program Files (x86)\Latitude Geographics\Geocortex Essentials\Default\REST Elements\REST folder had a notOverwrite="True" in the appSettings.  This is added when the post installation is started and then should be removed again when ‘Finish’ is clicked.  It looks like this was left in this file after I’d uninstalled Essentials.  After installing Essentials again it was still in the file.  Apparently this was a bug in version 4.1 of Essentials, so this must have been left behind from when that version was installed, even though we're now on 4.2.

    Solution: After running the post install, check this web.config file and if necessary remove the notOverwrite="True" in the appSettings.

    Hints:

     

    Pressing F12 when the browser is running provides a debug window at the bottom of it.  Select the Console to see any errors.

     

    Error 500 is not very helpful.  Use ‘localhost’ for the server name in the URL to get a more detailed error.

    Thank you all for your response. I tried all of those you mentationed. Unfortunately, our case may be caused by other reasons. There is no notOverWrite in our web.config file. I fully uninstalled the Essentials 4.2 and installed 4.3. However the problem still exists. I am going to get help from technical support and will post our solution when it is resolved. Thanks again.

    Thanks to Latitude support helping us found out the problem.

    Here is our problem: our server is inside the firewall, which blocked dojo library from ESRI that Geocortex uses. Once I added the http://*.arcgis.com to our trusted sites, the problem resolved.

    Thank you all for your help. Hope this may be able to help somebody else:)
