NullReferenceException after building the site
I've kind of resolved this to some extent.
Created a new site and did a diff with the web.configs of the new site and the old (broken) site.
Older site is now working, however without images. Any ideas?

The error indicates that you are missing the <episerver.common> section in your web.config
EPiServer.Common.Configuration.ConfigurationSectionBase`1.GetInstance(String sectionName) +295
EPiServer.Common.ImplementationModule.LoadCoreConfiguration() +10
EPiServer.Common.Settings.LoadSettings() +268

Probably an error in config files just like you guessed. I normally do the same thing as you did. Start with fresh config files from example sites that you know are working and change settings for VPP etc (this might be the cause of your missing images btw). Use WinMerge or similar tool to find the differences that you need to move from old config files to the new ones... This is usually faster than bashing your head against the wall trying to modify the existing if you don't locate the error right away...

Hi,
Thanks for your ideas. Appreciate it. :)
So I encountered this error again. I was working on another new site. I was changing the ProductPageTemplate.aspx.
Built the site in Debug mode. And it happened again. Exception is as follow:
[NullReferenceException: Object reference not set to an instance of an object.] EPiServer.Common.Configuration.ConfigurationSectionBase`1.GetInstance(String sectionName) +295 EPiServer.Common.ImplementationModule.LoadCoreConfiguration() +10 EPiServer.Common.Settings.LoadSettings() +268 EPiServer.Common.InitializationModule.Initialize(InitializationEngine context) +27 EPiServer.Framework.Initialization.ModuleNode.Execute(Action a, String key) +64 EPiServer.Framework.Initialization.InitializationEngine.InitializeModules() +751 EPiServer.Framework.Initialization.InitializationEngine.Initialize(HostType hostType) +168 EPiServer.Framework.Initialization.InitializationModule.Initialize(HostType hostType) +308 EPiServer.Framework.Initialization.InitializationModule.FrameworkInitialization(HostType hostType) +75 EPiServer.Framework.Initialization.InitializationModule.Application_BeginRequest(Object sender, EventArgs e) +46 System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +80 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +270
Does this mean I cant build the site? I did build few times without any issue. But suddenly I get this exception again. Any ideas?

I have installed Episerver Communities as well. Following config sections are getting removed from web.config after building.
<section name="episerver.common" type="EPiServer.Common.Configuration.EPiServerCommonSection, EPiServer.Common.Configuration" />
<section name="nhibernate" type="System.Configuration.NameValueSectionHandler, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" />
<section name="episerver.community" type="EPiServer.Community.Configuration.EPiServerCommunitySection, EPiServer.Community.Configuration" />

Hi,
The root config files (including web.config) are modified by the build transforms. Try inserting the config sections in config files located under the Configuration folder instead. That way it will be included in the final web.config located in the root directory, which will be used by the site.

Hi,
I'm trying out Episerver 7 currently and getting the following exception.
Object reference not set to an instance of an object.

What I was trying to configure Dynamic Content as per the following link: http://world.episerver.com/Documentation/Items/Developers-Guide/EPiServer-CMS/7/Dynamic-Content/Configuring-Dynamic-Content/
I've added the given user control and built the site using VS 2010. Then I've got the mentioned exception.
So, I removed the user control and the config section. But still I'm seeing the same exception. Any help would be highly appreciated.
