Arkadaşlar 3.0.1 kurdum ama admin.php hata verdi sorunu çözemedim.

Hata:

Warning:  require_once(ABSPATHwp-admin/includes/bookmark.php) [function.require-once]: failed to open stream: No such file or directory in /home/kemerfm/public_html/site.com/wp-admin/admin.php on line 10

Fatal error:  require_once() [function.require]: Failed opening required 'ABSPATHwp-admin/includes/bookmark.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/kemerfm/public_html/site.com/wp-admin/admin.php on line 10

wp-admin e giremiyorum site aktif ama wp-admin sayfasına girdigimde bu hatayı alıyorum
