Enocured site problems message before plain update to Drupal 4.3.6 to newest.
Some pages can be opened – some with errors.
I was backup files on time before update but now site is down with message about encored error on every page I was open.
Seems, problem associated with DB.
p.s.: after every update I do I have problem with views module. It’s broken every time and I need to reinstall in and recreate blocks manually.
Whats about Drupal stability? It’s horror.
