After i activate Typograph on new 2.7 WP version, only blank white screen appear.
In server logs it's look like:
[error] PHP Fatal error: Cannot redeclare post_class() (previously declared in /server/path/here/public_html/wp-includes/post-template.php:282) in /server/path/here/public_html/wp-content/themes/typograph/functions.php on line 157
I will use Jason tip to give "default" theme. Fortunately that's works for me.
