HTTP Error 500.21 - Internal Server Error

Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list.

This link provided a solution for the issue. There are two solutions on this page. The bottom solution that involves using aspnet_regiis.exe is the one that worked on my machine.

In case you are interested; This site lists the HTTP status codes for IIS 7.

Below are a few links to help out if you are receiving a similar error. But first, here is how I solved the issue.

In IIS go to whatever the app pool that running your website, click on "Advanced Settings", the set "Enable 32-Bit Applications" to True.

I found this answer here.

This site may also be of some use.

Hth.

1. Go to Project Properties by right clicking on the project and selecting Properties
2. Select Java Build Path from the left menu
3. Select the Source tab
4. You should see the gen folder referenced as well as the src folder (and potentially many others)
5. Simply click the gen folder and hit Remove
6. Then click Add Folder and select the folder to add it back to the project

Let me know if you are having further issues.

Fret no more. Change the following lines in your name-app.xml:

From:

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<application xmlns="http://ns.adobe.com/air/application/1.5">

To:

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<application xmlns="http://ns.adobe.com/air/application/2.0">

For those who cannot see the difference; I replaced the xmlns version number. If you would like a more in depth walk through then please go here.

<s:layout>
	<s:VerticalLayout />
</s:layout>

it generates a container around the rest of your components. Thus, whenever you try to align those components they are bound to the limits of the auto generated container. Which means you will get something like this:

This is bad. So, how do you fix it? This is how:

<s:layout>
	<s:VerticalLayout horizontalAlign="center" verticalAlign="middle" />
</s:layout>

Which yields…

This annoyed me for a solid 30 minutes. Hope it helped you.

This is the entire application I was working in while figuring this out.

Every organisation makes mistakes running their website; the nature of those mistakes varies, however, depending on the size and type of organisation. Institutional websites are often large unwieldy creatures plagued by bureaucracy. In this talk Paul will share some of the harsh truths surrounding these websites and suggests ways to tame the beast!

Ten harsh truths about institutional websites from Paul Boag on Vimeo.

First, download Visual Studio Color Theme Editor. It is a theme editor specifically for Visual Studio that is maintained by Microsoft. Second, follow the instructions in this post and download the Expression Color Theme. That post also describes how to switch between themes so be sure to read carefully. Lastly, visit this post to download the .vssettings for the Metroline color scheme. This color scheme will colorize the xml/csharp/javascript/etc. If you are unhappy with the font size and font style then simply go to Tools > Options > Environment > Fonts and Colors to change them accordingly.

As for my configuration, I chose the Dark theme in the Theme Editor along with the Metroline color scheme. They compliment each other well.

You may have to restart Tweetdeck a time or two for it to work. I had to restart it just once.
