Admin Login Page Blank

I am having trouble accessing one of my wordpress sites, it runs fine for visitors, but when I try to log in via wp-admin I just get a blank page (http://www.inkpantry.com.

I’ve searched for solutions and have tried the following without success

1. Renaming Plugins Folder
2. Adding “DirectoryIndex index.html index.htm index.php” to the htaccess file
3. Looking for error logs (there are none at all)
4. Updating wordpress via ftp

Can anyone help me out?
