[support] Have no access to menus on two of my sites

Hello all, For weeks now I cannot access the ADMIN/MENU page for my two largest sites, culturekitchen and The Daily Gotham. culturekitchen is a Drupal install (Drupal 4.6). The Daily Gotham is a CivicSpace install (with drupal 4.5). This is what I get for both pages whenever i try to access them :

Fatal error: Maximum execution time of 30 seconds exceeded in /home/ liza/domains/dailygotham.com/public_html/includes/bootstrap.inc on line 331

Any ideas as to what is causing this? / liza
