ELMAH 1.2 Works great on CASSINI but I'm not able to make it works on IIS 7.5

I use asp.net 4 and C# as logging error solution I use ELMAH 1.2.

I was able to use properly ELMAH on my local computer using CASSINI in Visual Studio 2010 but I as soon I move the website to a Server with IIS 7 or IIS 7.5 (locally or remotely) ELMAH is not able to record any errors. No error or yellow pages show up.

I suppose there is some problem with configurations, even I read many tutorials I'm still not able to make it works on production environment. Here my Web.Config. Could you tell me what I'm doing wrong?

NOTES: I removed here the connection string for security, but on cassini work great Thanks

One difference between the configuration I use & the one you use, is your modules section is missing a property runAllManagedModulesForAllRequests="true"; that is, my modules section is as follows:

<modules runAllManagedModulesForAllRequests="true">
    <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" />
    <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah" preCondition="managedHandler" />
    <add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah" preCondition="managedHandler" />
    <add name="IIS7AppVersioningModule" type="IIS7AppVersioningModule.AppVersionModule,IIS7AppVersioningModule" />
</modules>
