HTTPS Redirect Umbraco Package Infinite Redirect Loop

Sources:
I was having this exact same issue with v1.2.0, and spent some time looking at my IIS set-up and certificates and everything was correct but the redirect kept on happening. What was strange was it worked locally but not on my staging environment.
My solution was to changes the host names set-up in Umbraco.
On my local environment (that worked) I had this set-up in "Manage Host Names":
sub.domain.local/en
But on staging (that wasn't working) I had:
So on staging I change this to:
sub.domain.com/en
This worked! So check your hosts names.

Umbraco css folder always modifying files in background without me touching them

I have a GIT repository and I'm using Umbraco. Once strange thing that was happening to me were my files in the css folder kept on being modified even though I wasn't changing them. So every time I wanted to commit a change I'd have to undo the css file changes.

I thought this was Umbraco and because I had my style sheet linked to the rich text editor datatype, but it turned out to be the uSync package. I was synchronizing Stylesheets so by turning this off in the uSyncSettings.config file this stopped the problem. I don't need uSync to manage these files for me.

Umbraco Relationships Datatype

This is a great Umbraco package that helps manage node relationships in multilingual websites. It's just what I was looking for:

Umbraco fails to Publish! We get an exception within a load balanced environment.

After a deployment to our live servers which are load balanced we could not Publish. We could Save but not right-click publish or by clicking on the icon.

This was the error:

ERROR Umbraco.Web.UmbracoApplication - [Thread 36] An unhandled exception occurred
System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.TypeInitializationException: The type initializer for 'umbraco.presentation.cache.dispatcher' threw an exception. ---> System.NullReferenceException: Object reference not set to an instance of an object.

This seemed to be an error with the distributed call from server 1 to server 2 in the load balancer.

  1. First I thought it might be a rewrite rule in \config\UrlRewriting.config - it wasn't
  2. Then I recycled the app pools - this didn't help
  3. I then made sure I could access the Umbraco web service on both servers:
    1. http://serverip1/umbraco/webservices/CacheRefresher.asmx - worked
    2. http://serverip2/umbraco/webservices/CacheRefresher.asmx - worked
  4. I disabled distributed calls and then Publish worked, but this wasn't a solution
  5. Finally the solution was due to incorrect config in \config\umbracoSettings.config. I somehow didn't have the <user>0</usertag:

<distributedCall enable="true">

How do I copy files after Publish to the Publish folder using Visual Studio 2010 with MSBuild?

My web project in Visual Studio 2010 has post-build events that copies files from a folder into the bin directory of the web project. But when I publish my site, MSBuild seems to ignore the post-build events and these files are NOT copied.

The solution is to create a BAT file that executes from a MSBuild Target. I called my BAT file PostBuildEventPublish.bat and it lives in my solution folder. This is the BAT file contents:

xcopy "%1References\UmbracoCourier.lic" "%2" /y
xcopy "%1References\jumps.umbraco.usync.dll" "%2" /y

The parameters %1 and %2 are input from the MSBuild csproj file. In VS2010 unload your web project and edit the project then insert this Target (at the bottom):

<Target Name="AfterPublish" AfterTargets="CopyAllFilesToSingleFolderForPackage">    
    <Exec Command="$(SolutionDir)References\PostBuildEventPublish.bat &quot;$(SolutionDir)&quot; &quot;$(ProjectDir)obj\$(Configuration)\Package\PackageTmp\bin&quot;" />
    <Message Importance="Normal" Text="Finished PostBuildEventPublish.bat" />
 </Target>

Obviously change to the paths you want to use.

As you can see parameter %1 = $(SolutionDir)
and parameter %2 = $(ProjectDir)obj\$(Configuration)\Package\PackageTmp\bin

You will notice that my Target always gets executed before the actual publish files are copied. 

C:\Dev\Puma\Main\References\PostBuildEventPublish.bat "C:\Dev\Main\" "C:\Dev\Puma\Main\Web\obj\Debug\Package\PackageTmp\bin"
C:\Dev\Puma\Main\References\UmbracoCourier.lic
1 File(s) copied
C:\Dev\Puma\Main\References\jumps.umbraco.usync.dll
1 File(s) copied
Finished PostBuildEventPublish.bat

Publishing folder Views...
========== Build: 5 succeeded or up-to-date, 0 failed, 0 skipped ==========

========== Publish: 1 succeeded, 0 failed, 0 skipped ==========

So parameter %2 is where the magic happens. Here we copy the files into the temp publish folder and when Publish completes copying the files to the actual Publish folder these post-build files will also be copied.

IIS7 not serving pages (ASPX) but just displays a blank page

I created a new IIS website with ApplicationPoolIdentity as the identity and .NET framework set to v4.0. In my hosts file I set my localhost to point to my test.dev domain (127.0.0.1 test.dev). When I tried viewing the site all I got back as a blank page.

What I tried: 

1. Installing all IIS components as I thought I might have missed some - this didn't help
2. Add full control permissions to my web folder for the ApplicationPoolIdentity (http://stackoverflow.com/questions/7334216/iis7-permissions-overview-applicationpoolidentity) - this didn't help
3. Registered .NET 4 with this command: C:\Windows\Microsoft.NET\Framework\v4.0.30319 C:\Windows\Microsoft.NET\Framework\v4.0.30319> aspnet_regiis.exe -i - This WORKED!!!
