I recently upgraded one of my site from Drupal 5 to Drupal 6 and found that the books and book pages were lost.

Recently one of my sites was upgraded to Drupal 5.7 from 5.1 and I was get a 404 or page not found error on all pages of my website except the front page. How I solved this.

I had a strange problem on this site. Every time I try to search it gave me "Page Cannot be Found"

Luckily there is an easy fix to this problem in 5.1.

If you are unable to login after you have upgraded.

if that doesnt work try adding the following line to your settings.php

ini_set('session.cookie_domain', '.example.com');
