Mistakes

In trying to keep a fast server I upgraded to PHP 5.3 as 5.2 in no longer supported, and all my Drupal 5 sites came up with Error.

As I have speed up all Drupal 6 and 7 site with Memcache and it's all working now, I working on patching or updating them the 6 asap.

So if you got Drupal 5 sites on server you need to think about upgrading your PHP to 5.3
