When I try to log in via the <domain>/user panel on my Drupal install (after I click login), the page displays this DB error:
Additional uncaught exception thrown while handling exception. Original PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away: SELECT filename FROM {registry} WHERE name = :name AND type = :type; Array ( [:name] => context_export_ui [:type] => interface ) in _registry_check_code() (line 3073 of /srv/www/banting/drupal-wet/includes/bootstrap.inc).

PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away in _drupal_session_write() (line 209 of /srv/www/banting/drupal-wet/includes/session.inc).I'm afraid I might be missing some key configurations for MySQL. Any ideas?
