Some of web.config for the site:

<system.serviceModel>
  <serviceHostingEnvironment>
        <baseAddressPrefixFilters>
            <add prefix="http://www.roros.kommune.no/"/>
            <add prefix="www.roros.kommune.no/"/>
            <add prefix="item"/>
            <add prefix="http://www.roros.kommune.no/templates/eDemokrati/Services/"/>
            <add prefix="www.roros.kommune.no/templates/eDemokrati/Services/"/>

        </baseAddressPrefixFilters>
    </serviceHostingEnvironment>

What is the error caused by and how do I solve this?

Answer 1

As the exception message indicates, relative URI is not allowed. Try removing the prefix="item" and make all of them an absolute URI.
