If i go to our www version it works but if i go with either our https or regular http it doesnt work. It just shows a blank page with nothing on it.

I have set the following but it still doesn't work with http/https.:

Do i need to set anything else for this to work?

What error do you get? Do you get anything at all?

It just shows me a blank white page. If i do "View page source" it's completely blank, not even a -tag or anything.

Also no error messages are recorded in the global.asax and no redirect to any error page. It just shows a blank white page.

Try getting it to run under all host headers under standard HTTP first - then worry about SSL...

But the webpage itself shows up if i remove the www. (Both http:// and https:// works without www.) Shouldn't the entire webpage be affected by the IIS headers?

Btw. the rest of the site is running .NET 4.5 MVC.

Determining whether or not to respond to a web URL that has a subdomain (www) or not is at the IIS server level. Either your web.config from your .NET 4.5 application is stomping on the YAF configuration or your YAF is not properly configured. You may try isolating the YAF application into it's own pool and assigning it an ASP.NET 4.0 pool. YAF is not MVC compatible as far as I know. Even this scenario is an IIS configuration issue --
