Community Server on Windows 2008


When you’ve installed Community Server on Windows 2008 and especially are running under IIS7, you’ll probably get some problems with at least your tags. Community Server will throw a 404 “Page not found” error on tags with spaces. If that’s the case, open up your web.config and paste the following code at the bottom, but within the “configuration” tags.



  <requestFiltering allowDoubleEscaping=true />



Now IIS7 might still throw an error because the configuration won’t allow you to overrule the default setting. In this knowledge base article you’ll find more information.

Find the following file %windir%System32inetsrvconfigapplicationHost.config and open it in Notepad under Administrator permissions. Find the key ‘requestFiltering’ and set overrideModeDefault to “Allow” instead of “Deny”.


When your avatars aren’t showing, it might be because you’re running in “Classic .NET AppPool” mode and not in “Integrated Pipeline”. Change it and it should work.

    Yeah, running into the “Tag Cloud” problem when spaces are in the tag name on my site.

    I made the change you recommended here, and I had seen repeated somewhere else, but that didn’t fix it, so I assume that the applicationhost.config file needs changing… but since I’m running at, I’m sure they’ll say “No.” :-<

    Any ideas of how this might be fixed outside of that? Since I'm running the "Express" edition, I don't have sources to modify.

    That’s probably because GoDaddy turned off the feature that you can change IIS settings from the web.config.

    So there’s probably no way to fix this, unless you’d contact GoDaddy yourself
