Drupal 5 upgrade

After a encountering a puzzling problem with slow page load times on 2 Drupal 4.7 sites, we upgraded to Drupal 5. The only remaining problem I can find is a css problem with the DiggThis Module. QuickTags crapped out too.

Amazingly, the template didn't break. Not too bad, anyway.

One problem we did encounter was drupal was reporting the taxonomy module to be "missing". Untrue - looking at the server folders. Found several posts referring to php versions & possible incompatibilities - but that didn't make sense as there are other 5.x sites (fresh install) on the same server.

The answer is here: http://drupal.org/node/128471 ... at least it worked here.
