 * According to its header, monster-ru.monstersproductions.com is using WordPress
   2.0.1.
 * However, the function being called, wp_get_current_user(), wasn’t introduced 
   into WordPress until version 2.0.3. So it sounds like somehow you ended up with
   some newer files (perhaps in a failed attempt to upgrade?)
 * I recommend that you upgrade to the latest version (2.0.4) and that you follow
   [these detailed instructions](http://codex.wordpress.org/Upgrading_WordPress#Detailed_Instructions)
   in doing it.
