Sitecore 7: Troubleshooting "Duplicate site definition: autohaus"

Intro:

After installing Sitecore 7 with the demo autohaus I started to separate the CS project in single folders.

Now I have the 3 Autohaus.* projects, a solution folder with the .sln file. A html folder for the clickdummy. Deployment targetfolder. Misc for miscellaneous, and 2 standard framework I need for my work.

Problem:

Now i was heading to this error. Well my local domain is autohaus/

Duplicate site definition: autohaus.

Solution:

I commented to following out from WWW.Autohaus.config file.

<!-- commented out

           <site name="autohaus" patch:before="*[@name='website']" virtualFolder="/" physicalFolder="/" rootPath="/sitecore/content" startItem="/autohaus" database="web" domain="extranet" allowDebug="true" cacheHtml="true" htmlCacheSize="10MB" registryCacheSize="0" viewStateCacheSize="0" xslCacheSize="5MB" filteredItemsCacheSize="2MB" enablePreview="true" enableWebEdit="true" enableDebugger="true" disableClientData="false" />

          -->

OK backend is up and running but not autohaus in the frontend. To get autohaus as default I copy the string above, removed  patch:before="*[@name='website']" and renamed name="autohaus" to name="website"

e.g.

<site name="website" virtualFolder="/" physicalFolder="/" rootPath="/sitecore/content" startItem="/Autohaus" database="master" domain="extranet" allowDebug="true" cacheHtml="true" htmlCacheSize="10MB" registryCacheSize="0" viewStateCacheSize="0" xslCacheSize="5MB" filteredItemsCacheSize="2MB" enablePreview="true" enableWebEdit="true" enableDebugger="true" disableClientData="false" />

Now it works. Happy

This solution is mit the best. Better is to Check the App_config/include Folder for right config and Check for the duplicate entry. See

WWW.Autohaus.debug.config

Or

WWW.Autohaus.local.config
