Hi Rikard,
Yes, the blank login page is exactly what I’m trying to fix. You can also try /wp-login.php which at least shows you the login form, but it too fails to work.

I’d like to be able to get you to a place where you can log in, but the only way I can do that is by switching to the default theme. We currently have ads going to the site, so if we were to do that we’d need to coordinate so that it would only be switched for a short while, while you were looking.

Removing the code from my .htaccess file does not solve the problem. The reason I have that code there is that if someone goes to http://wewhistle.com it does not redirect to https:// without it.

I’m open to suggestions! :)
