ELMAH – MVC 3 – 403 – Forbidden: Access is denied

(This is all from the documentation/getting started)

You don’t need the following line:

routes.IgnoreRoute("elmah.axd");

The next line takes care of it.

Everything you need to configure is in your web.config file. Something like:

<elmah>
  <security allowRemoteAccess="yes" />
  <errorLog type="Elmah.SqlErrorLog, Elmah" connectionStringName="mySqlConnString" />
</elmah>
<location path="elmah.axd">
  <system.web>
    <authorization>
      <allow roles="Administrator" />
      <deny users="*" />
    </authorization>
  </system.web>
</location>

Should get you going.
