Fehler in Drupal 7 Demo auf Drupalcenter

Hallo!

Vor der Anmeldung bekomme ich folgende Fehlermeldung:

PDOException: SQLSTATE[HY000]: General error: 145 Table './web1db3/accesslog' is marked as crashed and should be repaired: INSERT INTO {accesslog} (title, path, url, hostname, uid, sid, timer, timestamp) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7); Array ( [:db_insert_placeholder_0] => [:db_insert_placeholder_1] => node [:db_insert_placeholder_2] => http://www.drupalcenter.de/node/add/forum/370 [:db_insert_placeholder_3] => 91.179.8.18 [:db_insert_placeholder_4] => 4 [:db_insert_placeholder_5] => 19055ccbf9a5f24821f14ba5003243a4 [:db_insert_placeholder_6] => 448 [:db_insert_placeholder_7] => 1288116025 ) in statistics_exit() (Zeile 85 von /var/www/web1/web/drupal-7-demo/modules/statistics/statistics.module).
Auf der Website ist ein unvorhergesehener Fehler aufgetreten. Bitte versuchen Sie es später nochmal.

Nach der Anmeldung wird es dann hierzu:

* Notice: Undefined property: stdClass::$cache in DrupalDatabaseCache->prepareItem() (Zeile 396 von /var/www/web1/web/drupal-7-demo/includes/cache.inc).
