I have encountered a problem with my Drupal 5.3 site [www.PortofKnoxville.com] where whenever I am logged in as the Administrator, I am unable to access the "Administer" page using the Administer link in the navigation bar. Whenever I try, I get "Page not found".
Fortunately, I discovered that if I click "Edit primary links" (which appears at the top of my site whenever I am logged in as the Administrator), I am taken to the "Menus" page. From there, using the menu options on the side, I can get to each of my administration pages. I have no idea what suddenly caused this. The only thing I can say is that it happened right after I ran a manual Cron. Can anyone tell me how to fix this?
