define SHORTINIT true

[dugi digitaly]

​wp-blog-header.php
insert: if ( SHORTINIT ) return false; to line 13 or move the wp() function.
because: wp() function call to $wp->main(..)
but $wp not created if SHORTINIT == true

wp-blog-header.php is not the correct file to include in SHORTINIT mode, wp-load.php is.
