WP-Login Page does not load

Hello,

I am unable to access my WP-Login page. It doesn’t load and all I get is a blank page. Furthermore, I can’t view my blog either. I get that same blank page. I’ve attempted to upload a new wp-login.php file and I’ve disabled my plugins by renaming my folder to plugin.hold. However, I’ve met no success. Any ideas?

I use Yahoo webhosting.

Thanks 🙂
