Had drupal 7.9 working, have the required modules and a bit of taxonomy completed Just now, 8:30 pm, used drush up to update to drupal 7.10 now I get :

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request. -------------

I changed nothing, just did the drush update which I have done previously.

Can someone please advise what has gone wrong and how I should fix the problem, I appreciate any help thank you Roger
