I used the "Drupal on ISPConfig" howto to install Drupal into a site. I then create the administrator account (which then sends a password to me via email). Now whenever I try to login, Drupal takes the login an shows me a page - but the next link I click gives me an Access Denied response. On the Drupal site I see many people are having this problem, but there appears the dozens of possible answers. This leads me to believe there are dozens of possible causes. This setup worked fine when I had an earlier ISPConfig setup of Ubuntu 6.06 LTS, Apache2, MySQL4, PHP4. Now I am on Debian 3.1, Apache2, MySQL5, PHP5. In both cases I was using the Drupal 4.7.3 and the Drupal Howto. I am continuing to search the Drupal site for clues, but hope someone here may have seen this problem.
