I'm running Umbraco 7.2.2 on a node balanced site (NLB) with central file system. The site works fine on localhost but the back office is broken on my staging server.

What did you do?

  • Upgraded site to version 7.2.2. -- This overwrites an edit to ExamineSettings.config that was using the UmbracoExamine.TempStorage.dll, as per the requirement for a load balanced set up.
  • In ExamineSettings.config, set useTempStorage = LocalOnly on all Indexers and Searchers (see [http://issues.umbraco.org/issue/U4-5993 this issue])
  • Published site to central filesystem
  • Deleted /App_Data/TEMP files
  • Restarted both nodes.

What did you expect to happen? I expected the backoffice to work.

What actually happened? The front end loads fine, but I get a blank screen when accessing the back office and failed GET attempt from LazyLoad.js when it tries to access DEpendencyHandler.axd

Later on I get this error: Uncaught Error: No module: ngTable

According to [https://our.umbraco.org/projects/backoffice-extensions/spectrum-colour-picker/general/61573-Broken-in-Umbraco-722-with-debug-=-false this page] and several other issues around the net, my problem here was due to some security update in the 7.2.2 version of ClientDependancy that seems to have issues with query strings. By checking the package.manifests in /App_Plugins/, I discovered that one of my packages (MemberListView) was using query strings. I removed this package and everything seems to work again.

And copied that reply here:

When a JS file has a query string in it, CDF treats it as an external/request based resource, not a local file system resources since a local file path doesn't have a query string. CDF will not make external/request based resource calls unless you whitelist your domain, so you can fix this by white-listing your domains in the CDF config:


Shannon Deminick 18 Mar 2015, 07:32:20

The actual problem for this however is the way that we parse the values in the manifest. Unfortunately in the Umbraco core we've sort of bypassed how CDF is supposed to work. The fix is to let CDF do it's job and output the dependencies correctly. In these cases, any dependency that declares a query string is treated as an external dependency and will be loaded in separately instead of trying to be part of the CDF bundles.

I've had my primary domain white-listed since before the release of 7.2.2 and still ran into this issue. Our site runs on a subdomain and my white-list looks like: bundleDomains="localhost:12345,.mysite.edu"

But I assume the fix in 7.2.3 does not rely on the white-list.

Sebastiaan Janssen 18 Mar 2015, 13:11:50

Yes, the querystrings problem is fixed independently of the domains, it will work without whitelisting.

Shannon Deminick 18 Mar 2015, 23:02:16

Of course in the meantime you can just remove the query string from the dependency listing in the package.manifest that is causing the issue (there shouldn't ever be query strings for local resources in the package manifest!)

Hi everyone,

I'm experiencing same issue and I just cannot get it to work.

I'm using Umbraco 7.1.8 and this issue happens on all Umbraco 7.1.8. projects that I've worked on.

I have tried literary everything.

  • changing IIS compression
  • Updating Client Dependancy
    • updating version
    • upgrading version number
    • setting bundle domains
  • updading all Umbraco Client folder
  • restarting, recycling APP pool
  • updating web.config
    • system.webserver -> handlers
    • security -> request filtering
  • ...
  • I have downloadend latest Umbraco (7.2.6), setup the site but the problem is still appearing.

Please, do you have any suggestions?

Kind regards, Nevena

@nevena - you'll need to provide more details. You must be seeing some sort of error, etc... in your browser's console. Can you please describe 'your' issue? When logging bug reports its best to include every bit of detail since your issue is probably actually different to someone elses.
